caffe调试之caffeheatmap：make matcaffe

Problem:

 $ make matcaffe cannot find lopencv_imgcodecs

Solution:

reinstall opencv3.0.0and add "opencv_imgcodecs" to makefile.

接下来在caffeheatmap目录下：

make cleanmakemake matcaffe 

matcaffe编译成功后：

make mattest

出现invalid mexfile错误：

原因是Caffe用系统的opencv编译，但是运行matcaffe时链接了matlab的opencv版本
