MATLAB Library Loading

Note   It is important to understand the difference between the following: MATLAB loadlibrary function — Loads shared library into MATLAB. Operating system loadlibrary function — Loads specified Windows or UNIX operating system module into the address space of the calling process.

With MATLAB Compiler version 4.0 (R14) and later, you can use MATLAB file prototypes as described below to load your library in a compiled application. Loading libraries using H-file headers is not supported in compiled applications. This behavior occurs when loadlibrary is compiled with the header argument as in the statement:

loadlibrary(library, header)

In order to work around this issue, execute the following command at the MATLAB command prompt:

loadlibrary(library, header, 'mfilename', 'mylibrarymfile'); 

where mylibrarymfile is the name of a MATLAB file you would like to use when loading this library. This step only needs to be performed once to generate a MATLAB file for the library.

In the code that is be compiled, you can now call loadlibrary with the following syntax:

loadlibrary(library, @mylibrarymfile, 'alias', alias)

With MATLAB Compiler versions 4.0.1 (R14+) and later, generated MATLAB files will automatically be included in the CTF file as part of the compilation process. For MATLAB Compiler versions 4.0 (R14) and later, include your library MATLAB file in the compilation with the -a option with mcc.

Caution   With MATLAB Compiler Version 3.0 (R13SP1) and earlier, you cannot compile calls to loadlibrary because of general restrictions and limitations of the product.
