Back-substitution step of parallel linear inversion involving Banded matrix and Y-Vectors.

Parameters
[in]mythe number of rows assumed for A and length of Y-vectors stored in V
[in]mah1the left half-bandwidth of fortran array A
[in]mah2the right half-bandwidth of fortran array A
[in]mxnumber of parallel Y-vectors inverted
[in]aencodes the (L)*(D**-1)*(U) factorization of the linear-system matrix, as supplied by subroutine LDUB or, if N=NA, by LDUB
[in,out]vinput as right-hand-side vectors, output as solution vectors
