Hallo,

octave has the builtin functions "conv" (or "fftconv") for the
discrete convolution of two vectors and "fft" for the discrete
fourier transform of a vector.

Are there also functions (maybe in octave-forge?) which compute
the *continuous* convolution (\int_0^x f(x-y)g(y)dy or 
\int_{-\infty}^\infty f(x-y)g(y)dy) and the *continuous* fourier
transform of functions?

Thanks,

Christoph Dalitz
