in octave
repmat([],2,3) works well:
ans = [](0x0)
I guess in MATLAB too
but numpy tile() can't handle it correctly:
>>> from numpy import *
>>> tile(array([1]), (2,3))
array([[1, 1, 1],
[1, 1, 1]])
>>> tile(array([]), (2,3))
Traceback (innermost last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.5/site-packages/numpy/lib/shape_base.py", line
623, in tile
c = c.reshape(-1,n).repeat(nrep,0)
ValueError: total size of new array must be unchanged
(I have numpy 1.0.1)
