fem1d_display, an Octave code which reads a prefix defining a trio of files containing the nodes, nodal values, and elements for a finite element method (FEM) model, and displays a plot.
The finite element function is assumed to be defined by as a piecewise polynomial, which is continuous at the breakpoints, and which has the same degree within each breakpoint interval.

fd1d_display, an Octave code which reads a pair of files defining a 1d finite difference model, and plots the data.
fem1d, a data directory of examples of 1d fem files, a set of three text files that can be used to describe many 1d finite element models;
fem1d, an Octave code which applies the finite element method to a linear two point boundary value problem in a 1d region.
fem1d_adaptive, an Octave code which applies the finite element method to a linear two point boundary value problem in a 1d region, using adaptive refinement to improve the solution.
fem1d_function_10_display, an Octave code which reads a prefix defining three finite element data files, reads the data, samples the finite element function, and displays a plot.
fem1d_nonlinear, an Octave code which applies the finite element method to a nonlinear two point boundary value problem in a 1d region.
fem1d_pmethod, an Octave code which applies the p-method version of the finite element method to a linear two point boundary value problem in a 1d region.
