Partial Diﬀerential Equations in MATLAB P. Howard Spring Contents is, the functions c, b, and s associated with the equation should be speciﬁed in one M-ﬁle, the functions p and q associated with the boundary conditions in a second M-ﬁle (again, keep in. MATLAB x = Anb to solve for Tn+1). From a practical point of view, this is a bit more From a practical point of view, this is a bit more complicated than in the 1D case, since we have to deal with “book-keeping” issues, i.e.
