Back-substitution step of linear inversion involving row-Vector and Banded matrix.
- Parameters
-
[in] | m | the number of rows assumed for A and columns for V |
[in] | mah1 | the left half-bandwidth of fortran array A |
[in] | mah2 | the right half-bandwidth of fortran array A |
[in,out] | v | input as right-hand-side row-vector, output as solution vector |
[in] | a | encodes the (L)*(D**-1)*(U) factorization of the linear-system matrix, as supplied by subroutine LDUB |
