Hello all,
I am new to maxima and I am very impressed by its capabilities.
The particular problem I am trying to solve at the moment needs some
manipulation of Fourier transforms. I have seen that FFT and Fourier
series are available within Maxima. I have read through the "Maxima
Manual" and "The Maxima Book" but I can't find a way to do this.
Is there a general way to perform integral transforms? Or I do I have to
"define" them myself? Something like:
FT:F(w):=integrate(f(t)*exp(-%i*2*%pi*w*t),t,-INF,INF);
ev(FT,f(t):=sin(t*t));
doesn't seem to work.
Actually, I would like to work with FT, but also other kinds of integral
transforms, like time-frequency, or convolution products.
Thanks for your help.
