Function fourier_eigenfunctions
Source pub fn fourier_eigenfunctions(t: &[f64], m: usize) -> FdMatrix
Expand description
Compute Fourier eigenfunctions on [0,1].
The Fourier basis consists of:
- φ_1(t) = 1
- φ_{2k}(t) = √2 cos(2πkt) for k = 1, 2, …
- φ_{2k+1}(t) = √2 sin(2πkt) for k = 1, 2, …
§Arguments
t - Evaluation points in [0,1]m - Number of eigenfunctions
§Returns
FdMatrix of size len(t) × m
