claw/applications/euler/1d/shockentropy

Euler equations with a shock wave hitting a sinusoidal variation in
entropy  (i.e. variation in density with constant pressure)

This standard test problem was introduced in

   C.-W.  Shu and S. Osher,
   Efficient implementation of essentially non-oscillatory shock
     capturing schemes II,
   J. Comput. Phys. 83 (1989), 32-78


To plot a comparison of fine and coarse grid solutions,
first run code in subdirectory qref, then in main directory.

When you plot the results in the main directory (./shockentroy), the
reference solution will also be plotted for comparison with the
coarse grid solution.

m-files updated to be compatible with Version 4.2 matlab files.
