Update of bug #50884 (project octave):
Status: None => Works For Me

Follow-up Comment #1:
Well isnumeric, isstruct, isreal, iscomplex, etc, all test the properties of
an entire array and return a single logical value.
The Matlab function ishandle, and the Octave extensions isaxes and isfigure,
operate elementwise on the given array, so they return an array with the same
dimensions as the input array. This is more comparable to the isfinite or
isinf functions than isnumeric.
Think of isaxes, isfigure, and ishandle more like
>> [1 2 3] > 0
ans =
1 1 1
>> [] > 0
ans = [](0x0)
