Usage

###Load a tensor from matlab array

local matio = require 'matio'
testTensor = matio.load('test.mat', 'var_a')

Calling MATIO C functions

All MATIO C functions are available in the matio.ffi. namespace returned by require. The only difference is the naming, which is not prefixed by Mat_ anymore.

For example, look at matio.load in init.lua
