WebSo when we are comparing the execution time of a MATLAB script to that of a MEX file, we are comparing the amount of time it takes the MATLAB script to be interpreted to the amount of time it takes the generated C/C++ code to execute. Now it is reasonable to think that compiled C code should execute faster than M code is interpreted.

For example: I'm doing some Optimal Control with fmincon() and some complicated dynamics. If I run everything as *.m files one run of the solver takes 67-70 seconds. If I MEX the dynamics file the same run only takes 9 seconds.

WebI have solved this by writing C-MEX functions. They are hardcoded pure C without any comfort of Matlab. I cannot imagine that the Code can produce comparable speed, but writing an testing C code is a dry work.
