Trsm¶
Triangular solve with multiple right-hand sides: performs
\(C := \alpha A^{-\#} B\), or
\(C := \alpha B A^{-\#}\), depending upon whether side was
chosen to be LEFT or RIGHT, respectively. Whether \(A\) is treated
as lower or upper triangular is determined by uplo, and \(A^{-\#}\)
can be \(A^{-1}\), \(A^{-T}\), or \(A^{-H}\) (and diag determines
whether \(A\) is treated as unit-diagonal or not).
Note
For the best performance, A and B should both be in [MC,MR] distributions.
