STRING_SIMULATION is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version.
BVP4C, MATLAB programs which illustrate how to use the MATLAB command bvp4c(), which can solve boundary value problems (BVP's) in one spatial dimension.
FD1D_WAVE, a MATLAB program which applies the finite difference method to solve a version of the wave equation in one spatial dimension.
