DiagonalScaleTrapezoid¶
Note
This is not a standard BLAS routine, but it is BLAS-like.
Performs either \(A := \mbox{op}(D) A\) or \(A := A \mbox{op}(D)\), where \(A\) is trapezoidal (upper or lower with the boundary diagonal of given offset), \(op(D)\) equals \(D=D^T\), or \(D^H=\bar D\), where \(D = \mbox{diag}(d)\) and \(d\) is a column vector.
