fem1d_sample, a MATLAB code which can evaluate a finite element function of one argument.
The current version of the program can only handle finite element meshes which are made of piecewise constant or piecewise linear basis functions.

fem1d_sample is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version.
fem1d, a data directory which contains examples of 1d fem files, three text files that describe a 1d finite element model;
fem1d, a MATLAB code which applies the finite element method to a 1d linear two point boundary value problem.
fem1d_adaptive, a MATLAB code which applies the finite element method to a 1d linear two point boundary value problem using adaptive refinement to improve the solution.
fem1d_display, a MATLAB code which reads three files defining a 1d arbitrary degree finite element function, and displays a plot.
fem1d_nonlinear, a MATLAB code which applies the finite element method to a 1d nonlinear two point boundary value problem.
fem1d_pmethod, a MATLAB code which applies the p-method version of the finite element method to a 1d linear two point boundary value problem.
fem2d_sample, a MATLAB code which evaluates a finite element function defined on an order 3 or order 6 triangulation.
fem3d_sample, a MATLAB code which evaluates a finite element function defined on 3d tetrahedral mesh.
histogram_data_2d_sample, a MATLAB code which demonstrates how to construct a probability density function (pdf) from a frequency table over a 2d domain, and then to use that pdf to create new samples.
histogram_pdf_sample, a MATLAB code which demonstrates how sampling can be done by starting with the formula for a pdf, creating a histogram, constructing a histogram for the cdf, and then sampling.
