Load pickle files in Matlab
Posted on June 12, 2013 by xcorr
It’s easy enough to load .mat files in Python via the scipy.io.loadmat function. But what about loading .pickle files into Matlab? That’s easy enough by calling a system command in Matlab, like so:
function [a] = loadpickle(filename)
if ~exist(filename,'file')
error('%s is not a file',filename);
end
outname = [tempname() '.mat'];
pyscript = ['import cPickle as pickle;import sys;import scipy.io;file=open("' filename '","r");dat=pickle.load(file);file.close();scipy.io.savemat("' outname '",dat)'];
system(['LD_LIBRARY_PATH=/opt/intel/composer_xe_2013/mkl/lib/intel64:/opt/intel/composer_xe_2013/lib/intel64;python -c ''' pyscript '''']);
a = load(outname);
end
Note that I’m setting the LD_LIBRARY_PATH environment variable since Matlab seems to reset this variable internally and it causes .so module import errors in Python.
