Computation structure: a PHP file (this page: 'P.slab.php') calls (via 'action=...') an intermediate PHP file ('Slab.php'), which (through $_POST) sends the problem data as command line arguments to an executable. # This last does the computing, and makes 'system' call(s) to 'gnuplot', for the final (temporary) web page.

Keywords: slabs; optimization; gnuplot.
