Convolving a vector with the 2nd derivative of a Gaussian [message #74071] Wed, 29 December 2010 11:37

I am trying to do something that must be straigtforward but I don't
seem to get my head around it.

I have a vector, say
A = [20, 20, 20, 21, 26, 48, 88, 105, 182, 182, 241, 245, 241, 182,
182, 105, 88, 48, 26, 21, 20, 20, 20, 20]

I want to convolve it with the 2nd derivative of a Gaussian with a
sigma of 10.

Is the CONVOL of IDL suitable anf how do I construct the kernel?

Help will be greatly apprecuated.
