zhemm() void zhemm ( char  side, char  uplo, int  m, int  n, doublecomplex  alpha, int  lda, doublecomplex  a[], int  ldb, doublecomplex  b[], doublecomplex  beta, int  ldc, doublecomplex  c[]  ) C <- αAB + βC or C <- αBA + βC (Hermitian matrix) (BLAS 3) Purpose This routine performs one of the matrix-matrix operations C <- alpha*A*B + beta*C or C <- alpha*B*A + beta*C where alpha and beta are scalars, A is a Hermitian matrix, B and C are m x n matrices. Parameters [in] side Specifies whether the Hermitian matrix A appears on the left or right in the operation as follows: = 'L': C <- alpha*A*B + beta*C. = 'R': C <- alpha*B*A + beta*C. [in] uplo Specifies whether the upper or lower triangular part of the Hermitian matrix A is to be referenced as follows: = 'U': Only the upper triangular part of the Hermitian matrix is to be referenced. = 'L': Only the lower triangular part of the Hermitian matrix is to be referenced. [in] m Number of rows of the matrix C. (m >= 0) (If m = 0, returns without computation) [in] n Number of columns of the matrix C. (n >= 0) (If n = 0, returns without computation) [in] alpha Scalar alpha. [in] lda Leading dimension of the two dimensional array a[][]. (lda >= max(1, m) when side = 'L', lda >= max(1, n) otherwise) [in] a[][] Array a[la][lda] (la >= m when side = 'L', la >= n otherwise) m x m Hermitian matrix A when side = 'L', or n x n Hermitian matrix A when side = 'R'. Only the upper or lower triangular part is to be referenced in accordance with uplo. [in] ldb Leading dimension of the two dimensional array b[][]. (ldb >= max(1, m)) [in] b[][] Array b[lb][ldb] (lb >= n) m x n matrix B. [in] beta Scalar beta. When beta is supplied as zero then C need not be set on input. [in] ldc Leading dimension of the two dimensional array c[][]. (ldc >= max(1, m)) [in,out] c[][] Array c[lc][ldc] (lc >= n) [in] m x n matrix C. [out] m x n output matrix.
