How to run matlab code in linux as script file?

Question

I am looking into running matlab script in Linux similar to bash/python scripts. I.e., a matlab script that can be run as an application.

You can get a similar effect without your custom mash script by adding the following header to the files you want to be executable:

#/usr/bin/bash
/path/to/matlab -r "$(sed -n -e '4,$p' < "$0")"
exit $?

If you want matlab to terminate after executing the script, as in your example, you could replace the second line with

sed -n -e '4,$p' < "$0" | /path/to/matlab

The idea here is to execute a bash command that simply clips off the header of the script, and passes the rest along to matlab.

Here is the implementation I came up with -

Create /usr/bin/mash script file containing the following lines -

#!/bin/bash

grep -ve '^(#!\|^\s*$)' ${@: -1} | ${@: 1:$#-1}     
exit $?

Write matlab script file called test.msh

#!/usr/bin/mash /usr/local/MATLAB/R2012a/bin/matlab -nodisplay

format long

a = 2*pi           % matlab commands ...

Run test.msh

$ ./test.msh 

...

>> >>  a =

Don't put it is /usr/bin; /usr/local/bin is a better place. /usr/bin is distribution-managed folder (or should be).

When you have code blocks inside lists, you need 8 indentation instead of 4 ;).
