How to apply Command line arguments in matlab

Hi,

I have matlab function that I want to use with different input file in every run.

Also, I want to convert it to exe file and run the script standalone from matlab.

Any Ideas how to do this?

Hi Tal,

Does the answer provided by Yash answer your question?

Or do you have a different workflow?

The MATLAB website has a worked-through example with instructions on how to compile a simple application and how to deploy it on another computer. In essence, you need to install the MATLAB Compiler Runtime together with your application. The installer for the runtime should already be present in your MATLAB compiler installation.

To pass command-line arguments to a MATLAB executable, you define a single MATLAB function in the executable. The arguments to the function are taken from the command line parameters (the first command-line parameter is the first argument, and so on).

For example, create a file

echo.m

with the following contents:

function exitcode = echo(a,b)
display(a)
display(b)
exitcode = 0;
end

You can then compile this file and run it with

echo 1 2 3

and it will print

 a=1 b=2

Read up on how to use varargin(). Pull the command line words out of varargin.

As far as I've been able to tell, vargin() is just used for writing functions that can take a variable number of input arguments; I haven't found anything on how to use this to pull words from command line input arguments.

I'm running my code as

matlab -nodisplay -r "myFile"

and want to be able to input two file paths and a number as command line arguments.

You need to use the name of your m-file, not "matlab -nodisplay". For example

myapp "C:\user\Serena\Documents\your data folder"
