### matlab *.m files to solve the heat equation.

If these programs strike you as slightly slow, they are. They would
run more quickly if they were coded up in C or fortran. As matlab
programs, would run more quickly if they were compiled using the
matlab compiler and then run within matlab.

This solves the heat equation with explicit time-stepping, and finite-differences
in space. The domain is [0,2pi] and the boundary conditions are periodic.
