OSTI ID:6504720
A code for solving stiff systems of ordinary differential equations is modified in order to make it more suitable for solving large stiff systems where the Jacobian is a block tridiagonal matrix. Such systems often arise when the method-of-lines is used to solve two-dimensional partial differential equations. 16 refs.
