Computational Mathematics:
- This program represents the 2-D Laplacian operator in the wave equation ?2a/?t2 = c2 ?2a by an extremely simple 5-point difference formula. The designated objects alter the value of the local wave speed c and each of 2562 uniform grid points is updated on each time step by about 5 lines of Fortran code. The program runs in real time and gives graphic output as it executes.
