今天跑程序时遇见需要安装matio 错误，整理了一下
/home/s408/torch/install/bin/luajit: /home/s408/torch/install/share/lua/5.1/trepl/init.lua:389: module 'matio' not found:No LuaRocks module found for matio
no field package.preload['matio']
安装流程
1，下载
路径matio,哪个版本都可以，自己选择
2，安装
$ tar zxf matio-1.5.13.tar.gz
$ cd matio-1.5.13
$ ./configure
$ make
$ make check
$ make install
3，出错
s408@s408:~/matio-1.5.13$ make install
Makefile:697: recipe for target 'install-libLTLIBRARIES' failed make[1]: *** [install-libLTLIBRARIES] Error 1
' Makefile:1428: recipe for target 'install-am' failed make: *** [install-am] Error 2
。。。。
4，解决
新建一个文件夹将你解压后的matio包放进去，
`s408@s408:~$ cd matio-1.5.13/
s408@s408:~/matio-1.5.13$ mkdir _install
s408@s408:~/matio-1.5.13$ ./configure --host=arm-hisiv500-linux --prefix=/home/s408/soft/matio-1.5.13/_install/（你安装的位置）
Features --------------------------------------------
MAT v7.3 file support: no
Extended sparse support: yes
Packages --------------------------------------------
zlib: -lz
hdf5:
MATLAB:
在执行make install 即可，到此安装完了，
我在用Torch跑数据时出现错误，因此还需要一步
/home/s408/torch/i/torch/install/share/lua/5.1/trepl/init.lua:389: module 'matio' not found:No LuaRocks module found for matio
。。。。。。
到你新建存放的目录下，输入命令
s408@s408:~/soft$ luarocks install matio
