stdlib_dtrmm Subroutine

public pure subroutine stdlib_dtrmm(side, uplo, transa, diag, m, n, alpha, a, lda, b, ldb)

DTRMM performs one of the matrix-matrix operations B := alphaop( A )B, or B := alphaBop( A ), where alpha is a scalar, B is an m by n matrix, A is a unit, or non-unit, upper or lower triangular matrix and op( A ) is one of op( A ) = A or op( A ) = A**T.
