The package is aimed at Mathematica users who wish to use some MATLAB functionality in their Mathematica programs. It is the most complete package of this type that we are aware of. It is open source, released under the MIT license.
What it does:
* Transfers data between Mathematica and MATLAB. Most MATLAB data types are supported, including sparse arrays, structs and cells.
* Allows wrapping MATLAB functions and making them seamlessly callable from Mathematica. The functions arguments are automatically translated.
What it does not do:
* It won't let you call Mathematica from MATLAB
A small taste of what is possible with MATLink:
