[SciPy-User] Laplacian of a matrix (MATLAB del2 function eqv. in NumPy)

[Juan Luis Cano]

Hello everybody, I would like to calcute de Laplacian Operator of a 
matrix with spacing between points and if it were possible the same 
boundary conditions as the function del2 does in Matlab. I am already 
aware of this SO question

http://stackoverflow.com/q/4692196/554319

but scipy.ndimage.filters.laplace() 
<http://docs.scipy.org/doc/scipy/reference/generated/scipy.ndimage.filters.laplace.html> 
is not suitable because a) none of its modes contemplates extrapolation 
on the boundary and b) doesn't allow change spacing between the points. 
Another person suggested a direct translation of the code but doesn't 
work correctly. This translation option is a bit bothering because the 
original code is somewhat difficult to follow. Is there any other 
possibility?

I wish you could help me. Thanks in advance.
