PTRANS

 
Solves the transpose of a factored system, for a tridiagonal matrix. The matrix
must first be factored using NAPACK subroutine PFACT.
 
Classes  :  D2a2a . Solution of systems of linear equations, including matrix
                  inverses, and LU and related factorizations (real
                  nonsymmetric tridiagonal matrices)
 
Type     : Fortran subroutine in NAPACK package.
Access   : Some uses prohibited. Portable.
Precision: Single.
 
Usage    : CALL PTRANS (X, A, B)
