[SciPy-user] Creating a 2D matrix with a gausian hump?

the code was not attached... but this time!
btw: you won't get values == 0 at the borders of your (n X m) kernel grid,
since in that case you could use a kernel (n-2 X m-2).
that is the reason, why the attached code worked like using the multiples
of the sigmas of the gaussians as the limits of the kernel definition
since one also provides the step sizes of the data-grid, the kernel-size
may vary wrt. the multiples of the sigmas.
