Raw synthetic waveform data for a 1D space-time varying medium that "computes its own inverse"

In this matlab .mat file (generated with the '-v7.3' flag) there are 5 variables:

p_all -- 2d array of double-precision wavefield values (main output of calculations described in a forthcoming publication)

cm -- 2d array of double-precision medium property values (space-time varying p-wave velocity of the 1D medium)

rm -- 2d array of double-precision medium property values (space-time varying mass-density of the 1D medium)

dt_eff -- effective time sampling step in milliseconds (sampling step along the first dimension / row direction)

dx_eff -- effective space sampling step in meters (sampling step along the second dimension / column direction)
