fd1d_advection_lax_test

fd1d_advection_lax_test, 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 method for the time, writing graphics files for processing by gnuplot.
