MATLAB

K-d树实现。采用matalb和C++混合编译的方式实现。(kdtree provides a minimalistic implementation of kd-tree. The implementation can be used either inside MATLAB by means of MEX calls, or as a standalone tool, directly a C/C++ program. )

这是姜启源教授在清华大学讲解数学建模课程的资料，对于数学建模由入门到精通十分有用(lecture in math modeling,given by Professor JiangQiyuan )

This is a simple sample of crypto
