CPGULUBackSub Method
Solve a linear system using LU decomposition and back-substitution.

Available since Oasis montaj version: 5.0.0
License: Available to anyone with an Oasis Montaj license.  

Namespace: Geosoft.Desktop.GXNet
Assembly: geosoft.desktop.gxnet (in geosoft.desktop.gxnet.dll)
Notes
Solves the system Ax = b for a given b, using the LU decomposition of the matrix a The LU decomposition and the permutation vector are obtained from LUBackSub_PGU. Pagers and VVs must be type REAL except for the permutation vector, which should be INT
