matio库

使用开源matio库来读取rcpr_COFW.mat文件的矩阵数据。matio的源码可从这里下载

###1.编译matio库

1.下载依赖库zlib和HDF5(windows下编译好的HDF5自带zlib库)。HDF5可以从这里下载，下载预先编译好的动态库版本并进行安装

2.安装完后添加系统变量HDF5_DIR，其值为HDF5的安装目录，例如D:\Program Files (x86)\HDF_Group\HDF5\1.8.13，并将库的bin目录加入系统环境变量PATH中，%HDF5_DIR%\bin

###准备编译环境

官方现在只提供了win64的二进制编译，用的opencv2.4.9 Qt5.x.x（不知道Qt的具体版本- -！）

我们使用32位编译，需要一个VC编译器（版本不要太低) 下载Qt5,OpenCV,两者的版本不是很大的问题,opencv自带了32位和64位,而Qt是分开,Qt下载32位。

我们还需要CMake来生成Makefile用来编译。
