fem_neumann, a MATLAB code which sets up a time-dependent reaction-diffusion equation in 1d, with Neumann boundary conditions, discretized using the finite element method (FEM).
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 (FEM) to a linear two point boundary value problem in a 1d region.
fem1d_function_10_display, a MATLAB 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, a MATLAB code which applies the finite element method (FEM) to a nonlinear two point boundary value problem in a 1d region.
fem1d_pmethod, a MATLAB code which applies the p-method version of the finite element method (FEM) to a linear two point boundary value problem in a 1d region.
fem1d_sample, a MATLAB code which samples a scalar or vector finite element function of one variable, defined by fem files, returning interpolated values at the sample points.
