STRING_SIMULATION, a C program which simulates the behavior of a vibrating string by solving the corresponding initial boundary value problem (IBVP), creating files that can be displayed by gnuplot.

STRING_SIMULATION is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version.
FD1D_WAVE, a C program which applies the finite difference method to solve a version of the wave equation in one spatial dimension.
gnuplot_test, C programs which illustrate how a program can write data and command files so that gnuplot can create plots of the program results.
HIGH_CARD_SIMULATION, a C program which simulates a situation in which you see the cards in a deck one by one, and must select the one you think is the highest and stop; the program uses GNUPLOT for graphics.
