Matrix from Python to MATLAB


I'm working with Python and MATLAB right now and I have a 2D array in Python that I need to write to a file and then be able to read it into MATLAB as a matrix. Any ideas on how to do this?

If you use numpy/scipy, you can use the function:

import numpy,

arr = numpy.arange(10)
arr = arr.reshape((3, 3))  # 2d array of 3x3'c:/tmp/arrdata.mat', mdict={'arr': arr})

Now, you can load this data into MATLAB using File -> Load Data. Select the file and the arr variable (a 3x3 matrix) will be available in your environment.

Note: I did this on scipy 0.7.0. (scipy 0.6 has savemat in the module.) See the latest documentation for more detail
