Ok, I just double-checked the source for plot_wireframe().  It does not
perform any broadcasting (which I consider to be a bug).

Until it is fixed, you will have to do the broadcasting yourself:

X= np.ones((1, 45))
Y= np.zeros((32, 1))
x, y = np.broadcast_arrays(X, Y)

Which produces x and y with the same shapes, and their values duplicated in
the direction the array was "expanded".

Pass those into plot_wireframe().
