pde: Numerical solver for a special case of the Telegrapher PDE

In shill1729/telegrapher: Study the telegrapher PDE and process numerically

Description

A basic implicit scheme implementation for the formal analog of the Fokker-Planck equation in Minkowski space with one space dimension and sign convention -, +. The initial condition is the dirac delta function and the initial velocity is zero.

Usage

pde(x0, tt, N, M, sp = 1, xScale = 1, f = NULL)

Arguments

x0	initial point in space
tt	the time horizon
N	the time resolution (number of time sub-intervals)
M	the space resolution (number of space sub-intervals)
sp	the speed of light
xScale	scale up or down the space interval (x_0-ct, x0+ct)
f	the initial condition as a function of the space coordinate

Value

list of the time-grid, space-grid, and solution matrix.
