Fourier transform
hi all,
a part of Fourier series coefficients (see here), there is a function in the Prime (or XCas) to get the Fourier Transform (not FFT) and its inverse? See in Wolfram Alpha, for example... If not, I need help to make a program. We could calculate it via laplace() (Laplace transform), but we need the "bilateral laplace transform" and I don't know how to get it with the Prime... F[f(t)] == bilateralL[f(t)] where \( s=i\omega \) Thank you Salvo EDIT: the general equation should be \[ \int_{\infty }^{\infty }f(x) e^{i\omega t}dt \] but with Prime I get often "undef" and if I set "complex" in CAS I get "Limit: Max order reached or unable to make series expansion Error: Bad argument" ∫aL√0mic (IT9CLU) :: HP Prime 50g 41CX 71b 42s 39s 35s 12C 15C  DM42, DM41X  WP34s Prime Soft.
