Thinking I could use fromfunction to generate the x,y,z coordinates of a
3D surface, I instead got separate arrays of x, y, and z coordinates (as
I should have expected) and needed to use a nested listcomp to produce
the unified array of 3D points:
x,y,z=fromfunction( lambda i,j: (xfun(i,j),yfu
Using numpy-1.0.2/python-2.5/winxp pro sp2: in the following, the only
array is 'a', and I'm not using it as an index, so why do I get the
IndexError below?
--- start python session ---
>>> a=array([[1,3],[2,4]])
>>> a
array([[1, 3],
[2, 4]])
>>> f=lambda i,j: a[i,j]
>>> f(1,1)
4
