gpl_display


gpl_display, a MATLAB code which tries to read the data in a typical gnuplot GPL file, describing a 1D, 2D or 3D curve, or a surface Z(X,Y) defined on a regular grid, a triangular grid, or an irregular quadrilateral grid, displays it in a more attractive way than gnuplot is capable of.

GNUPLOT does not do a very good job of displaying 3D surfaces. It sketches them out with lines, or some simple solid surfaces. In some cases, MATLAB can take the same data and make a much more attractive image. This set of programs tries to read a few typical GPL data files, and display them appropriately.
