it looks like repmat is not there anymore... why? use numpy.repeat and numpy.tile, instead! hth, lorenzo. On 4/30/07, dmitrey <openopt@ukr.net> wrote:

It's not on the matlab page simpy because numpy.tile didn't exist when the page was created. It should be fixed. But repmat is still there in numpy.matlib (I think that was what it was called.) --bb On 4/30/07, dmitrey <openopt@ukr.net> wrote:

In numpy, the equivalent function is called tile:
from numpy import * a = array([[1,2],[3,4]]) tile(a, (2,3)) array([[1, 2, 1, 2, 1, 2], [3, 4, 3, 4, 3, 4], [1, 2, 1, 2, 1, 2], [3, 4, 3, 4, 3, 4]])
I note that http://www.scipy.org/NumPy_for_Matlab_Users advertises repmat instead of tile. (repmat is in numpy.matlib, a compatibility wrapper library) Maybe this should be fixed? -- Pauli Virtanen
