fd1d_display, a MATLAB code which reads a prefix defining a pair of files containing the nodes and values for finite difference data, and displays a plot.
The program is designed for cases in which the independent variable data ranges over a single dimension, either of space, or of time.
Thus, it can be used to display results from a steady-state model of heat, a 1D time-independent boundary value problem, or the time variation of a predator-prey system in which there is no spatial variation.
fd1d_display ( 'prefix' )where 'prefix' is the common filename prefix of:

fd1d_display is available in a MATLAB version.
fd_predator_prey, a MATLAB code which applies a finite difference approach to a predator-prey system with time dependence and no spatial variation.
fd1d, a data directory of examples of 1d fd files, a set of two text files that can be used to describe many 1d finite difference models;
fd1d_bvp, a MATLAB code which applies the finite difference method to a two point boundary value problem in one spatial dimension.
fd1d_heat_steady, a MATLAB code which uses the finite difference method to solve the steady (time independent) heat equation in 1d.
fd1d_wave, a MATLAB code which applies the finite difference method to solve the time-dependent wave equation in one spatial dimension.
fem1d_display, a MATLAB code which reads a trio of files defining a 1d finite element model, and plots the data.
