用Matlab编写的梅克斯文件比相应的m文件慢了近300倍。

I started implementing a few m-files in C++ in order to reduce run times. The m-files produce n-dimensional points and evaluate function values at these points. The functions are user-defined and they are passed to m-files and mex-files as function handles. The mex-files use mexCallMATLAB with feval for finding function values.I started implementing a few m-files in C++ in
