dsymm(side, uplo, m, n, alpha, a, lda, b, ldb, beta, c, ldc): void
computes a scalar-matrix-matrix product with one symmetric matrix and
adds the result to a scalar-matrix product defined as
C := alpha * A * B + beta * C
or
C := alpha * B * A + beta * C
where A is a symmetric matrix
computes a scalar-matrix-matrix product with one symmetric matrix and adds the result to a scalar-matrix product defined as C := alpha * A * B + beta * C or C := alpha * B * A + beta * C where A is a symmetric matrix
