when this error rise?index 28 is out of bounds for axis 0 with size 13

[deanhystad]

Here's a simpler example:

import numpy as np
hg=np.zeros([13,29])
for i in range(29):
    for j in range(13):
        hg[i][j] = 1*13+j

Output:
Traceback (most recent call last):
  File "...", line 5, in <module>
    hg[i][j] = 1*13+j
IndexError: index 13 is out of bounds for axis 0 with size 13

See the problem now? Look at the values for i and the shape of hg.

There may be other problems.
