W_kernel {rbbnp}

Define the inverse Fourier transform function of W

Description

Define the inverse Fourier transform function of W

Usage

W_kernel(u, L = 10)

Arguments

u

A numerical value or vector representing the time or space domain.

L

The limit for numerical integration, defines the range of integration as [-L, L]. Defaults to 10.

Value

A numerical value or vector representing the inverse Fourier transform of the infinite order kernel at the given time or space point(s).
