Matlab functions for converting back and forth between Numpy ndarray objects and Matlab matrices

mat2np.m

function npary = mat2np(mat)

% convert matlab matrix to python (Numpy) ndarray 
sh = fliplr(size(mat));
mat2 = reshape(mat,1,numel(mat));  % [1, n] vector
npary = py.numpy.array(mat2);
npary = npary.reshape(sh).transpose();  % python ndarray

end

np2mat.m

function mat = np2mat(npary)

% convert python (Numpy) ndarray to matlab
sh = double(py.array.array('d',npary.shape));
npary2 = double(py.array.array('d',py.numpy.nditer(npary)));
mat = reshape(npary2,fliplr(sh))';  % matlab 2d array 

end

The last line of mat2np should enforce matlab to use integers, so size is not converted to floats:
npary = npary.reshape(int32(sh)).transpose();
