copied!<p>As mentioned previously by answerers, you can call a live copy of MATLAB from C via the <a href="http://www.mathworks.com/access/helpdesk/help/techdoc/index.html?/access/helpdesk/help/techdoc/matlab_external/f38569.html&http://www.mathworks.com/access/helpdesk/help/techdoc/helptoc.html" rel="nofollow noreferrer" title="MATLAB Engine">MATLAB Engine</a> interface.</p> <p>If the end-product needs to be used where there is no live copy of MATLAB, you can deploy the application using <a href="http://www.mathworks.com/products/compiler/" rel="nofollow noreferrer" title="MATLAB Compiler">MATLAB Compiler</a>. However, MATLAB Compiler does not, as another answer has suggested, convert MATLAB programs into C code (and hasn't done for a few versions now). Instead, it archives and encrypts your MATLAB program, and packages it into an executable or shared library that executes against the MATLAB Compiler Runtime (shareable royalty-free). The executable or shared library can then be called from C.</p> <p>Alternatively you could go the other way around, and call your C code from MATLAB, using either <a href="http://www.mathworks.com/access/helpdesk/help/techdoc/index.html?/access/helpdesk/help/techdoc/ref/loadlibrary.html" rel="nofollow noreferrer" title="loadlibrary">loadlibrary</a> or MATLAB's <a href="http://www.mathworks.com/access/helpdesk/help/techdoc/index.html?/access/helpdesk/help/techdoc/matlab_external/bp_kqh7.html" rel="nofollow noreferrer" title="MEX interface">MEX interface</a>.</p> <p>Update: As of release R2011a, you can also use <a href="http://www.mathworks.com/products/matlab-coder" rel="nofollow noreferrer">MATLAB Coder</a> to generate C code directly from a subset of the MATLAB language.</p>
