fem2d_scalar_display_test, a MATLAB program which calls fem2d_scalar_display() to read datafiles describing a set of nodes, their triangulation, and the value of a scalar quantity at each node, and create a graphics file of the corresponding surface plot, which is then displayed using the MATLAB graphics system.

fem2d_scalar_display, a MATLAB program which reads information about nodes, elements and nodal values for a 2D finite element method (FEM) and creates a surface plot of U(X,Y), using the MATLAB graphics system.
ELL is an L-shaped region on which the function U=X^2+Y^2 is defined.
SPIKE is a circular region on which a solution of the Poisson equation forms an off-centered spike.
