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
