pdeval

Evaluate the numerical solution of a PDE using the output of pdepe

Syntax

Arguments

m
Symmetry of the problem: slab = 0, cylindrical = 1, spherical = 2. This is the first input argument used in the call to pdepe.
xmesh
A vector [x0, x1, ..., xn] specifying the points at which the elements of ui were computed. This is the same vector with which pdepe was called.
ui

A vector sol(j,:,i) that approximates component i of the solution at time and mesh points xmesh, where sol is the solution returned by pdepe.

xout

A vector of points from the interval [x0,xn] at which the interpolated solution is requested.

Description

[uout,duoutdx] = pdeval(m,x,ui,xout) approximates the solution and its partial derivative at points from the interval [x0,xn]. The pdeval function returns the computed values in uout and duoutdx, respectively.
