fem1d, a data directory which contains examples of 1D FEM files, three text files that describe a 1D finite element model;
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_bvp_linear, an Octave code which applies the finite element method, with piecewise linear elements, to a two point boundary value problem in one spatial dimension.
fem1d_display, an Octave code which reads three files defining a 1D arbitrary degree finite element function, and displays a plot.
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_lagrange, an Octave code which sets up the matrices and vectors associated with the finite element method (FEM) solution of a boundary value problem (BVP) -u''+u=f(x), using Lagrange basis polynomials.
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.
fem1d_sample, an Octave code which samples a scalar or vector finite element function of one variable, defined by FEM files, returning interpolated values at the sample points.
