ZTBSV

 
Solve one of the triangular systems, x = inv(A)*x, x = inv(trans(A))*x, x =
inv(ctrans(A))*x, where A is a triangular matrix in band storage mode, trans(A)
is the transpose of the matrix, and ctrans(A) is the conjugate transpose of the
matrix.
 
Classes  :  D2c2 . Solution of systems of linear equations, including matrix
                 inverses, and LU and related factorizations (complex
                 non-Hermitian banded matrices)
            D2c3 . Solution of systems of linear equations, including matrix
                 inverses, and LU and related factorizations (complex
                 non-Hermitian triangular matrices)
 
Type     : Fortran subroutine in IMSLM library.

Implementation of ZTBSV from IMSLM on ITL

 
ITL:       Unix Workstation Network, National Institute of Standards and
           Technology (NIST), Gaithersburg, MD. Available to NIST staff.
 
Precision: Double. (Single: CTBSV)
 
Access available only to NIST staff on internal Unix systems. They may access this
package provided the /itl tree is cross-mounted.
