compiler.build.standaloneApplication

Create a standalone application for deployment outside MATLAB

Syntax

compiler.build.standaloneApplication(AppFile)

compiler.build.standaloneApplication(AppFile,Name,Value)

compiler.build.standaloneApplication(opts)

results = compiler.build.standaloneApplication(___)

Description

compiler.build.standaloneApplication(AppFile) creates a deployable standalone application using a MATLAB^® function, class, or app specified by AppFile. The executable type is determined by your operating system. The generated executable does not include MATLAB Runtime or an installer.

compiler.build.standaloneApplication(AppFile,Name,Value) creates a standalone application with additional options specified using one or more name-value arguments. Options include the executable name, help text, and icon image.

compiler.build.standaloneApplication(opts) creates a standalone application with additional options specified using a compiler.build.StandaloneApplicationOptions object opts. You cannot specify any other options using name-value arguments.

results = compiler.build.standaloneApplication(___) returns build information as a compiler.build.Results object using any of the argument combinations in previous syntaxes. The build information consists of the build type, paths to the compiled files, and build options.

Examples

Create Standalone Application

Create a standalone application using a function file that generates a magic square.

In MATLAB, locate the MATLAB code that you want to deploy as a standalone application. For this example, compile using the file magicsquare.m located in matlabroot\extern\examples\compiler.

appFile = fullfile(matlabroot,'extern','examples','compiler','magicsquare.m');

Build a standalone application using the compiler.build.standaloneApplication command.

compiler.build.standaloneApplication(appFile);

This syntax generates the following files within a folder named magicsquarestandaloneApplication in your current working directory:

• includedSupportPackages.txt — Text file that lists all support files included in the application.

• magicsquare.exe or magicsquare — Executable file that has the .exe extension if compiled on a Windows^® system, or no extension if compiled on Linux^® or macOS systems.

• run_magicsquare.sh — Shell script file that sets the library path and executes the application. This file is only generated on Linux and macOS systems.

• mccExcludedFiles.log — Log file that contains a list of any toolbox functions that were not included in the application. For information on non-supported functions, see MATLAB Compiler Limitations.

• readme.txt — Text file that contains information on deployment prerequisites and the list of files to package for deployment.

• requiredMCRProducts.txt — Text file that contains product IDs of products required by MATLAB Runtime to run the application.

• unresolvedSymbols.txt — Text file that contains information on unresolved symbols.

To run magicsquare from MATLAB with the input argument 4, navigate to the magicsquarestandaloneApplication folder and execute one of the following commands based on your operating system:

Operating System	Test in MATLAB Command Window
Windows	!magicsquare 4
macOS	system(['./run_magicsquare.sh ',matlabroot,' 4']);
Linux	!./magicsquare 4

The application outputs a 4-by-4 magic square.

     5    11    10     8
     9     7     6    12
     4    14    15     1

To run your standalone application outside of MATLAB, see Run Standalone Application.

Customize Standalone Application

Create a standalone application and customize it using name-value arguments.

Write a MATLAB function that uses a subfunction to compute the diagonal components of a magic square. Save the functions to files named mymagicdiag.m and mydiag.m.

function out = mymagicdiag(in)
X = magic(in);
out = mydiag(X);

function out = mydiag(in)
out = [diag(in)]';

Build the standalone application using mymagicdiag.m. Use name-value pair arguments to specify the executable name, add the mydiag.m function file, and interpret command line inputs as numeric doubles.

compiler.build.standaloneApplication('mymagicdiag.m',...
    'ExecutableName','MagicDiagApp',...
    'AdditionalFiles','mydiag.m',...
    'TreatInputsAsNumeric','On')

The function generates the following files within a folder named MagicDiagAppstandaloneApplication in your current working directory:

• includedSupportPackages.txt

• MagicDiagApp.exe or MagicDiagApp

• run_MagicDiagApp.sh (only on Linux and macOS systems)

• mccExcludedFiles.log

• readme.txt

• requiredMCRProducts.txt

To run MagicDiagApp from MATLAB with the input argument 4, navigate to the MagicDiagAppstandaloneApplication folder and execute one of the following commands based on your operating system:

Operating System	Test in MATLAB Command Window
Windows	!MagicDiagApp 4
macOS	system(['./run_MagicDiagApp.sh ',matlabroot,' 4']);
Linux	!./MagicDiagApp 4

The application outputs the diagonal entries of a 4-by-4 magic square.

Create Multiple Applications Using Options Object

Create multiple standalone applications on a Windows system using a compiler.build.StandaloneApplicationOptions object.

For this example, use the file magicsquare.m located in matlabroot\extern\examples\compiler.

appFile = fullfile(matlabroot,'extern','examples','compiler','magicsquare.m');

Create a StandaloneApplicationOptions object using appFile. Use name-value arguments to specify a common output directory, interpret command line inputs as numeric doubles, and display progress information during the build process.

opts = compiler.build.StandaloneApplicationOptions(appFile,...
    'OutputDir','D:\Documents\MATLAB\work\MagicBatch',...
    'TreatInputsAsNumeric','On',...
    'Verbose','On')

opts =

  StandaloneApplicationOptions with properties:

            CustomHelpTextFile: ''
              EmbedArchive: on
            ExecutableIcon: 'C:\Program Files\MATLAB\R2021b\toolbox\compiler\resources\default_icon_48.png'
            ExecutableName: 'magicsquare'
    ExecutableSplashScreen: 'C:\Program Files\MATLAB\R2021b\toolbox\compiler\resources\default_splash.png'
         ExecutableVersion: '1.0.0.0'
                   AppFile: 'C:\Program Files\MATLAB\R2021b\extern\examples\compiler\magicsquare.m'
      TreatInputsAsNumeric: on
           AdditionalFiles: {}
       AutoDetectDataFiles: on
           SupportPackages: {'autodetect'}
                   Verbose: on
                 OutputDir: 'D:\Documents\MATLAB\work\MagicBatch'

Build a standalone application by passing the StandaloneApplicationOptions object as an input to the build function.

compiler.build.standaloneApplication(opts);

To create a new standalone application using the function file example2.m with the same options, use dot notation to modify the AppFile of the existing StandaloneApplicationOptions object before running the build function again.

opts.AppFile = 'example2.m';
compiler.build.standaloneApplication(opts);

By modifying the AppFile argument and recompiling, you can create multiple applications using the same options object.

Get Build Information from Standalone Application

Create a standalone application and save information about the build type, generated files, included support packages, and build options to a compiler.build.Results object.

Compile using the file magicsquare.m located in matlabroot\extern\examples\compiler.

results = compiler.build.standaloneApplication('magicsquare.m')

results = 

              BuildType: 'standaloneApplication'
                  Files: {2×1 cell}
IncludedSupportPackages: {}
                Options: [1×1 compiler.build.StandaloneApplicationOptions]

The Files property contains the paths to the magicsquare standalone executable and readme.txt files.

Example: 'mymagic.m'

Data Types: char | string

opts — Standalone application build options

StandaloneApplicationOptions object

Standalone application build options, specified as a compiler.build.StandaloneApplicationOptions object.

Name-Value Arguments

Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: 'EmbedArchive','on'

AdditionalFiles — Additional files

character vector | string scalar | cell array of character vectors | string array

Additional files to include in the standalone application, specified as a character vector, a string scalar, a string array, or a cell array of character vectors. File paths can be relative to the current working directory or absolute.

Example: 'AdditionalFiles',["myvars.mat","myfunc.m"]

Data Types: char | string | cell

AutoDetectDataFiles — Flag to automatically include data files

'on' (default) | on/off logical value

Flag to automatically include data files, specified as 'on' or 'off', or as numeric or logical 1 (true) or 0 (false). A value of 'on' is equivalent to true, and 'off' is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

• If you set this property to 'on', then data files that you provide as inputs to certain functions (such as load and fopen) are automatically included in the standalone application.

• If you set this property to 'off', then you must add data files to the application using the AdditionalFiles property.

Example: 'AutoDetectDataFiles','Off'

Data Types: logical

CustomHelpTextFile — Path to help file

character vector | string scalar

Path to a help file containing help text for the end user of the application, specified as a character vector or a string scalar. The path can be relative to the current working directory or absolute.

EmbedArchive — Flag to embed standalone archive

'on' (default) | on/off logical value

Flag to embed the standalone archive, specified as 'on' or 'off', or as numeric or logical 1 (true) or 0 (false). A value of 'on' is equivalent to true, and 'off' is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

• If you set this property to 'on', then the function embeds the archive in the standalone executable.

• If you set this property to 'off', then the function generates the standalone archive as a separate file.

Example: 'EmbedArchive','Off'

Data Types: logical

ExecutableIcon — Path to icon image

character vector | string scalar

Flag to interpret command line inputs as numeric values, specified as 'on' or 'off', or as numeric or logical 1 (true) or 0 (false). A value of 'on' is equivalent to true, and 'off' is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

• If you set this property to 'on', then command line inputs are treated as numeric MATLAB doubles.

• If you set this property to 'off', then command line inputs are treated as MATLAB character vectors.

Example: 'TreatInputsAsNumeric','On'

Data Types: logical

Verbose — Flag to control build verbosity

'off' (default) | on/off logical value

Flag to control build verbosity, specified as 'on' or 'off', or as numeric or logical 1 (true) or 0 (false). A value of 'on' is equivalent to true, and 'off' is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

• If you set this property to 'on', then the MATLAB command window displays progress information indicating compiler output during the build process.

• If you set this property to 'off', then the command window does not display progress information.

Example: 'Verbose','On'

Data Types: logical
