Matlab Compiler

How to use Matlab Compiler on Linux

This section shows an example on how to use MATLAB Compiler to code and build standalone applications.

Magic Square Example

A magic square is an array of integers arranged so that their sum is the same when added vertically, horizontally, or diagonally. Copy the following code in a text-file and save it as magicsquare.m

Important: When this programm is runned in a Linux-Terminal, we have to use the function str2num (string to number). Arguments are used as strings, thats why they have to be converted in a number in Matlab.

Compile the magicsqure function (with the command: mcc) in a Linux-Terminal

To run the magicsquare programm we give the shell-script 2 arguments. The first is the path to the Matlab Compiler Runtime. The second is for the programm magicsquare itself.

More help on mcc: Enter on commandline: mcc -help

Limited amount of licenses

The number of MATLAB licences is limited. To ensure a fair and efficient usage of the licences throughout the ETH the following measures have been put in place:

What can you do?

  1. Compile your MATLAB program. The best approach to avoid excessive usage of MATLAB licences is to compile your MATLAB program. The resulting executable does not need ANY MATLAB licence! This frees you from all MATLAB licence restrictions and also allows you to provide your executable to users without a MATLAB installation.
  2. Exit MATLAB when finished. Only then will all used licences be given back.
  3. Register the need for many MATLAB licences due to a MATLAB course By registering your need in advance, we can take countermeasures and ensure that these licences are available.
  4. Buy your own MATLAB licences if you must have a guaranteed 24/7 service or if you need to use an excessive amount of licences.
