Matlab wrapper

[sglvladi]

Added a MatlabWrapper class that can be used to create/connect to MATLAB sessions, run MATLAB code and convert the input/output.

An example of how the class can be utilised to create a MatlabKalmanPredictor, that computes the Kalman prediction equations in MATLAB, has also been included.

Could you look at using this pytest import skip feature for the the Matlab test script.

@sdhiscocks Thanks for pointing me to the specific resource! I think it should be fixed now. Let me know if it looks ok.

We'll look to make this into a separate plugin.
