DiffEqs`FourierTools`

This package provides functions for computing partial sums of Fourier series.

FourierSum[f[x], {x, -L, L}, m]     returns the first m terms of the Fourier series of f[x] on [-L, L].      NFourierSum[f[x], {x, -L, L}, m]     returns the first m terms of the Fourier series of f[x] on [-L, L] with numerical coefficients.      FourierCosSum[f[x], {x, 0, L}, m]      returns the first m terms of the Fourier cosine series of f[x] on [0, L]. NFourierCosSum[f[x], {x, 0, L}, m]     returns the first m terms of the Fourier cosine series of f[x] on [0, L] with numerical coefficients. FourierSinSum[f[x], {x, 0, L}, m]     returns the first m terms of the Fourier sine series of f[x] on [0, L]. NFourierSinSum[f[x], {x, 0, L}, m]      returns the first m terms of the Fourier sine series of f[x] on [0, L] with numerical coefficients.
