I have obtained C code by converting the MATLAB code into C using mcc function. It is functioning very slow. How can I make it run fast like C?? I am using MATLAB 2009b.

Best Regards,
Sambhav.

The result of compiling is not C code in the sense that you appear to
believe.

some of your options:
-optimize the MATLAB code (vectorize/preallocate/better algo)
-after careful profiling, consider write mex routines for hot spots
-consider using EML (this is closer to your concept of 'obtaining C code'
-reimplement your algo in C from scratch
