fem2d_scalar_display_test


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