Define the Fourier transform of a infinite kernel proposed in Schennach 2004
Usage
W_kernel_ft(xi, xi_lb = 0.5, xi_ub = 1.5)
Arguments
- xi
A numerical value or vector representing the frequency domain.
- xi_lb
The lower bound for the frequency domain. Defaults to 0.5.
- xi_ub
The upper bound for the frequency domain. Defaults to 1.5.
Value
A numerical value or vector representing the Fourier transform of the infinite
order kernel at the given frequency/frequencies.
