I want to calculate the Fourier transform of some Gaussian function. Consider the simple Gaussian g(t) = e^{-t^2}. The Fourier transform of g(t) has a simple analytical expression , such that the 0...

I recently replaced Matlab with Python because I was real;y excited by Sympy. But now I have the following problem: I need a way to reliably calculate continuous fourier transforms with Python. S...

This is probably a very naive question but here it is. I want to calculate Fourier transform of a function f(x). So I define a numpy array X and pass through vectorized function f. Now if I calcul...

Consider a function f(t), how do I compute the continuous Fouriertransform g(w) and plot it (using numpy and matplotlib)? This or the inverse problem (g(w) given, plot of f(t) unknown) occurs if...

I think Sympy makes a mistake in calculating the Fourier transform of a trig function. For example: from sympy import fourier_transform, sin from sympy.abc import x, k print fourier_transform(sin(...
