Details
Front end for zoeppritz program.
Value
List output of zoeppritz call:
angle
Incident angles, degrees
rmat
Matrix of 4 by n reflection coefficients for each angle
rra
Matrix of 4 by n real part of scattering matrix
rra
Matrix of 4 by n imaginary part of scattering matrix
ang
Matrix of 4 by n phase angle
incw
integer, from input parameter
icoef
integer, from input parameter
alphacrit
critical angle
Note
This front end is easier to call because it is more verbose.
Creates a plot of the coefficients versus incident angle.
If coefficients are complex, they are replaced with NA
and they are thus not plotted.
