How to make MATLAB stand-alone application?

I have a small Matlab m file which uses matlab signal processing toolbox, it basically is filtering noise from my signals. I want to run it outside MatLab environment. How can I make it an exe file so that I can run it in dos?

here is my m file

[b,a] = butter(9,.02,'low'); x=textread('noisy.out'); y=filter(b,a,x); save filtered.out y -ASCII

my compiler is

Lcc C version 2.4 in

when I run the following command

mcc -m myfilter.m -o mehdi

to make exe file I get the following error

Error: File "myfilter" is a script M-file and cannot be compiled with the current Compiler.

please help me how I can resolve this problem?

At the top of your file, you need to add

function myfilter

to convert it from a script in to a function.

Note: I seem to recall that filter design was one of the things you are not allowed to compile, so I don't know if you will be able to compile calls to butter() .

I put function myfilter but did not work

do I need to use another compiler to make it work?

[Walter Roberson]

What happened when you added that line? What message(s) did you get?

You seem to be using Windows; which Matlab version are you using, and are you using the 32 bit or 64 bit version?

[maadi]

Yes I am using 32 bit windows.

I am trying to build a compiler as you see below

>> mbuild -setup

Please choose your compiler for building standalone MATLAB applications:

Would you like mbuild to locate installed compilers [y]/n? y

Select a compiler:

[1] Lcc C version 2.4 in D:\MATLAB7\sys\lcc

[0] None

Compiler: 1

Please verify your choices:

Compiler: Lcc C 2.4

Location: D:\MATLAB7\sys\lcc

Are these correct?([y]/n): y

Try to update options file: C:\Documents and Settings\Erik\Application Data\MathWorks\MATLAB\R14\compopts.bat

From template: D:\MATLAB7\BIN\WIN32\mbuildopts\lcccompp.bat

Done . . .

--> "D:\MATLAB7\bin\win32\mwregsvr D:\MATLAB7\bin\win32\mwcomutil.dll"

DllRegisterServer in D:\MATLAB7\bin\win32\mwcomutil.dll succeeded

--> "D:\MATLAB7\bin\win32\mwregsvr D:\MATLAB7\bin\win32\mwcommgr.dll"

DllRegisterServer in D:\MATLAB7\bin\win32\mwcommgr.dll succeeded

after setting up the dll files I use this command to make my exe file

mcc -m myfilter.m -o myfilter

But I fail and this is the error message I got

??? Error: File "myfilter" is a script M-file and cannot be compiled with the current Compiler.

Thanks

As Walter suggested, you need:

function myfilter

[b,a] = butter(9,.02,'low'); x=textread('noisy.out'); y=filter(b,a,x); save filtered.out y -ASCII

It doesn't seem like you've added function myfilter to the top of your script to convert it to a function.

@Walter: MATLAB Compiler should support the BUTTER function (see http://www.mathworks.com/products/compiler/compiler_support.html)
