When creating mex in MATLAB: error C3861: 'fmax': identifier not found

fmin and fmax are a C99 features.

Microsoft doesn't fully support the C99 standard.

You can use std::max and std::min from standard algorithm library instead, after all you write C++ program.

解决方法：在头文件中加入

#include <algorithm>
