Scripts are the simplest kind of code file because they have no input or output arguments. They are useful for automating series of MATLAB® commands, such as computations that you have to perform repeatedly from the command line or series of commands you have to reference.
You can create a new script in the following ways:
Highlight commands from the Command History, right-click, and select Create Script.
On the Home tab, click the New Script button.
edit function. For example,
(if the file does not exist) and opens the file
new_file_name is unspecified, MATLAB opens
a new file called
After you create a script, you can add code to the script and save it. For example, you can
save this code that generates random numbers from 0 through 100 as a script called
columns = 10000; rows = 1; bins = columns/100; rng(now); list = 100*rand(rows,columns); histogram(list,bins)
Save your script and run the code using either of these methods:
Type the script name on the command line and press Enter.
For example, to run the
On the Editor tab, click the Run button.
You also can run the code from a second code file. To do this, add a line of code with the
script name to the second code file. For example, to run the
numGenerator.m script from a second code file, add the line
numGenerator; to the file. MATLAB runs the code in
numGenerator.m when you run the second
When execution of the script completes, the variables remain
in the MATLAB workspace. In the
list remain in the workspace. To see a list
of variables, type
whos at the command prompt.
Scripts share the base workspace with your interactive MATLAB session
and with other scripts.
