MATLAB Compiler

Limitations and Restrictions

MATLAB Code

MATLAB Compiler 3.0 supports almost all of the functionality of MATLAB. However, there are some limitations and restrictions that you should be aware of. This version of the Compiler cannot compile

• Script M-files (See Converting Script M-Files to Function M-Files for further details.)
• M-files that use objects
• Calls to the MATLAB Java interface
• M-files that use input or eval to manipulate workspace variables

Note    input and eval calls that do not use workspace variables will compile and execute properly.

• M-files that use exist with two input arguments, for example:

• exist('foo','var')
  

• The single variable form works for filenames and functions only.

• M-files that dynamically name variables to be loaded or saved. This example is disallowed by the Compiler:

• x= 'f';
  load('foo.mat',x);
  

• M-files that load text files, for example:

• load -ascii sampling1
  

The Compiler cannot compile built-in MATLAB functions (functions such as eig have no M-file, so they can't be compiled). Note, however, that most of these functions are available to you because they are in the MATLAB Math Built-in Library (libmatlb).

In addition, the Compiler does not honor conditional global and persistent declarations. It treats global and persistent as declarations. For example:

• if (y==3)
      persistent x
  else
      x = 3;
  end
