STRING_SIMULATION is a FORTRAN77 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.
The computer code and data files described and made available on this web page are distributed under the GNU LGPL license.
STRING_SIMULATION is available in a C version and a C++ version and a FORTRAN77 version and a FORTRAN90 version and a MATLAB version.
FD1D_WAVE, a FORTRAN77 program which applies the finite difference method to solve a version of the wave equation in one spatial dimension.
GNUPLOT, FORTRAN77 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 FORTRAN77 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.
