The repeat appears to accpt only short boolean array as repat counters:
A array([1, 2, 3]) repeat(A, [1,1,1]) array([1, 2, 3]) U = array([1,1,1], type=Bool) U array([1, 1, 1], type=Bool) repeat(A,U) # OK array([1, 2, 3]) A = arange(100000) U = ones(100000, type=Bool) AA = repeat(A,U) # U is too long --- an error is generated
Traceback (most recent call last): File "<pyshell#90>", line 1, in -toplevel- AA = repeat(A,U) File "/usr/local/lib/python2.3/site-packages/numarray/generic.py", line 1066, in repeat return _repeat(_nc.array(array), repeats) File "/usr/local/lib/python2.3/site-packages/numarray/generic.py", line 1054, in _repeat newarray = array.__class__(shape=newshape, type=array._type) ValueError: new_memory: invalid region size: -384.
U = ones(100000) # It is OK if U type is an integer AA = repeat(A,U)

This turned out to be a problem with summing the bool array to get an element count for the result array from the repeat. This is fixed now in CVS. Regards, Todd
