D03PCF

 
Integrates a system of linear or nonlinear parabolic partial differential
equations (PDEs) in one space variable. The spatial discretisation is performed
using finite differences, and the method of lines is employed to reduce the PDEs to
a system of ordinary differential equations (ODEs). The resulting system is
solved using a backward differentiation formula method.
 
Classes  :  I2a1a . Parabolic partial differential equations in one spatial
                  dimension
 
Type     : Fortran subroutine in NAG library (D03 sublibrary).
