**fd1d_advection_lax_wendroff**,
a FORTRAN90 code which
calls fd1d_advection_lax(), which
applies the finite difference method to solve the time-dependent
advection equation ut = - c * ux in one spatial dimension, with
a constant velocity, using the Lax-Wendroff method for the time derivative,
writing graphics files for processing by gnuplot.

fd1d_advection_lax_wendroff, a FORTRAN90 code which applies the finite difference method (FDM) to solve the time-dependent advection equation ut = - c * ux in one spatial dimension, with a constant velocity, using the Lax-Wendroff method to treat the time derivative, writing graphics files for processing by gnuplot.
