imex

A MATLAB MEX to Eigen interface in C++

Overview

A header-only library written in C++ that provides various functions for easy conversions from mxArray pointers to Eigen objects and back. Inputs will be typecast automatically, if possible.

Running the example

The example demonstrates how inputs are automatically typecast depending on the requested Eigen type.

• Set the path to your Eigen installation in line 21 of gen_mex.m
• Run test_imex.m
• C should be equal to A (except for the datatype)

Disclaimer

This is a very basic library in its early alpha stage. A lot of features are yet to be implemented (e.g. Eigen::Array, Eigen::SparseVector, support of MATLAB logicals).

So far, the library has only been tested on MATLAB R2016a x64 on Windows 8/10 with the Microsoft Visual C++ 2010 Compiler and Eigen 3.2.1.
