Convolution Theory Explained | Physics PhD Student Gareth

[Something els]

Hi,

I am a Physics PhD student and am trying to understand the Convolution theory. My original background is Chemistry so I am finding the maths very difficult.

I work in condensed matter and want to generate a c++ code that will convolute some theoretical data I generate with a Gaussian, to simulate some experimental data.

I can do the first bits in c++ no problem, however I don't really know where to start with the convolution.

I was wondering if anyone knows the best sites, or books to read, or who can advise me on a walkthough of convolution.

Thanks

Gareth

Multiply the Fourier transforms! (then inverse Fourier transform it)
