F07VSF

 
(CTBTRS/ZTBTRS) solves a complex triangular band system of linear equations
with multiple right-hand sides, A*X = B, (transpose(A))*X = B or (A**H)*X = B.
 
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)
