hi, I trying to covert and .m file into code C using the emlc function, but when try to get code the code, I got the next message error

function varargout = tsp_ga(xy,dmat,popSize,numIter,showProg,showResult)

I'd like to convert the next .m file from this webpage.

http://www.mathworks.com/matlabcentral/fileexchange/13680-traveling-salesman-problem-genetic-algorithm

the message error is:

the function failed to compile, if you intended to compile the file %#eml directive in 'C/documents.............MATLAB/distmat.m' however if you wish to call out to matlab use eml.extrinsic ('distmat') before calling the function.

but to be honest, I have no idea what means that!!

is it possible do that? what I need to read to understand correctly, or what I need to check first?

thanks fellows matlab!

Not all MATLAB functions are supported for code-generation, please see MATLAB Language Subset for Code Generation. Please see the answer to this question about when to use coder.extrinsic (eml.extrinsic in older versions of MATLAB).
