[Mne_analysis] np arrays to Matlab?

[Mads Jensen]

Hi Maria,

The data has to be a dict to use "savemat", e.g.
     import numpy as np
     import scipy.io

     x = np.linspace(0, 2 * np.pi, 100)
     y = np.cos(x)

     scipy.io.savemat('test.mat', dict(x=x, y=y))

example is taken from 
http://stackoverflow.com/questions/10997254/converting-numpy-arrays-to-matlab-and-vice-versa

but also see 
http://docs.scipy.org/doc/scipy-0.14.0/reference/tutorial/io.html

best,
mads
