What is the equivalent of MATLAB’s repmat in NumPy

by

Here is a much better (official) NumPy for Matlab Users link – I’m afraid the mathesaurus one is quite out of date.

The numpy equivalent of repmat(a, m, n) is tile(a, (m, n)).

This works with multiple dimensions and gives a similar result to matlab. (Numpy gives a 3d output array as you would expect – matlab for some reason gives 2d output – but the content is the same).

Matlab:

>> repmat([1;1],[1,1,1])

ans =
     1
     1

Python:

In [46]: a = np.array([[1],[1]])
In [47]: np.tile(a, [1,1,1])
Out[47]: 
array([[[1],
        [1]]])
