Foil 16 Explicit Equations for ADI with NAS Benchmarks

From Spatial Differencing and ADI Solution of the NAS Benchmarks CPSP713 Case studies in Computational Science -- Spring Semester 1996. by Geoffrey C. Fox
This factorized Operator can now be solved in three steps:
Each step involves solution of a 5 by 5 block tridiagonal matrix
The matrix is tridiagonal -- not pentadiagonal -- as numerical dissipation with Ñ4U is only added to explicit RHS term in this approximation
