     heat1 solves the initial value problem for the heat equation on the
whole line, no boundary condtions. The initial data for heat1 is the 
function mfile ff.m

     heat2 solves an initial value problem for the heat equation on the
half line with either the homogeneous dirichlet or neumann condition at
x = 0.  The initial data is a piecewise constant constant function 
contained in heat2.m.
