GBMV performs one of the matrix-vector operations

y := alpha*A*x + beta*y, or y := alpha*A'*x + beta*y,

where alpha and beta are scalars, x and y are vectors and A is an m by n band matrix, with kl sub-diagonals and ku super-diagonals.

DTBSV solves one of the systems of equations

A*x = b, or A'*x = b,

where b and x are n element vectors and A is an n by n unit, or non-unit, upper or lower triangular band matrix, with ( k + 1 ) diagonals.

No test for singularity or near-singularity is included in this routine. Such tests must be performed before calling this routine.

DTPMV performs one of the matrix-vector operations

x := A*x, or x := A'*x,

where x is an n element vector and A is an n by n unit, or non-unit, upper or lower triangular matrix, supplied in packed form.
