Errata: Matlab stores its data in ColumMajor mode, not RowMajor.

Hi. It may be easier to write a mex file instead, and call that mex file from matlab. This is what I usually do with my code.

You can map the data from a matlab matrix (real or complex) with Eigen::Map<>. As far as I remember, Matlab buffers are already aligned,

so you can use Eigen::Aligned and RowMajor as well.

From there you can do whatever you want with Eigen, and return results to  matlab. 

If you still want to import a mat file from C++ then that is not an Eigen-specific topic, you may have to find a library that can deal with .mat file importing,

or write your own.

Cheers.
