spec_cmp.m :  Plots power spectrum from SEM2DPACK simulations
------------  and overplots 1D estimation using depth of sediment
              (contour plot)

spec1D_cplot.m :  Plots 1D estimation using depth of sediment (contour plot)
----------------

spec2D_cplot.m :  Plots power spectrum from SEM2DPACK simulation (contour plot)
----------------

spec1D.m :  Routine used by spec1D_cplot.m and by spec_cmp.m for
----------  1D spectral estimation using sediment depth data

ampli1D.m : 1D spectral estimation for a single fixed depth
-----------

rock_ampli.m : half-space amplification for a given incidence angle
