triangulation_order3_contour_test, a MATLAB program which calls triangulation_order3_contour() to read datafiles describing a set of nodes, their triangulation, and the value of a scalar quantity at each node, and create a color contour plot of the scalar.

triangulation_order3_contour, a MATLAB program which makes a contour plot of scattered data, or of data defined on an order 3 triangulation.
CHANNEL is a channel region 3 units wide and 1 unit high. A Stokes flow solver has computed the fluid velocity and pressure in the channel. The pressure is a scalar and can be plotted by this routine.
ELL is an L-shaped region.
ELL2 is the same as ELL, except we do not supply the elements. The program will work just the same, except it will compute triangular elements internally, and write a copy out as a file.
LAKE is a simulated lake with an island region.
