>>> 1.0**numpy.array([1,2,3])
array([ 1., 1., 1.])
>>> 1.0**numpy.mat([1,2,3])
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for ** or pow(): 'float' and 'matrix'
Why the restriction for matrices?
Same question for matrices conformable for broadcasting:
why not produce the equivalent of the array result?
Cheers,
Alan Isaac
