matio/mattorch

matlab生成的数据是 mat格式的，需要转换成torch使用的 t7格式。可以使用 mattorch实现，但我在OS X 系统中总是安装出错。

matio也可以实现matlab数据和torch数据的转换，matio-ffi

matio

安装

笔主2018年11月按GitHub上步骤安装出错。
#OSX
brew install homebrew/science/libmatio
#Ubuntu
sudo apt-get install libmatio2

luarocks install matio

错误如下：

Error: homebrew/science was deprecated. This tap is now empty as all its formulae were migrated.

出现的原因是homebrew/science的git路径变了(貌似是2018年3月更新)。

这个homebrew community discussion 提到的：

The formulae in Homebrew/science have been copied over (but are not maintained) at https://github.com/brewsci/homebrew-science . A new tap for bioinformatics formulae at https://github.com/brewsci/homebrew-bio.
? brew tap brewsci/bio
? brew tap brewsci/science
? brew untap homebrew/science

最终解决方案：
首先
brew tap brewsci/science
brew install libmatio
最后
luarocks install matio

使用
