How to mex "linprog" | Matlab DSP

Hi, I am running 1000's of simulations that call linprog in MATLAB. I have found that much of the computing time is spent in linprog. I have tried streamlining my code using vectorization, memory pre- allocation, and mex files when possible. However, when I try to "mcc -x linprog" I get the following error: "Warning: File: optim/private/diagnose Line: 179 Column: 22 The MATLAB Compiler does not currently support MATLAB object- oriented programming. References to the method "formula" will produce a run-time error." Does anyone know how to generate the mex equivalent of linprog in MATLAB? Thanks for your time!

Dear spottie, Just check whether this file is using any Instrument Control function in linprog.m Because MATLAB compiler doesn't support the functions of Instrument Control Toolbox. Just type depdir('Linprog') on Matlab command window. It'll display the list of directories used by Linprog.m file. If it's using any function from 'C:\MATLAB6p5\toolbox\matlab\iofun', means it is using Instrument Control Toolbox function and you can't use the mcc -x Linprog to generate the dll. If you will be able to generate the required dll, that dll will cause the Matlab to crash. Hope this will help.
