MATLAB function to initialize and call the solve_sps2d function, which implements a 2-D solution of the nonlinear wave equation using a psuedospectral / staggered A-B method, including attenuation modeled with two relaxation mechanisms. This example demonstrates harmonic generation within a plane wave given a B/A parameter of 5.2. To increase the distance of propagation, scale the sample grid (num_axpts) by a factor(s) of 2.( MATLAB function to initialize and call the solve_sps2d function, which implements a 2-D solution of the nonlinear wave equation using a psuedospectral /staggered A-B method, including attenuation modeled with two relaxation mechanisms.
