Detailed Description
BLAS Level 3 API.
her2k performs one of the matrix-matrix operations for a Hermitian rank-2k update
C := alpha*op( A )*op( B )^H + conj(alpha)*op( B )*op( A )^H + beta*C
where alpha and beta are scalars, op(A) and op(B) are n by k matrices, and C is a n x n Hermitian matrix stored as either upper or lower.
op( A ) = A, op( B ) = B, and A and B are n by k if trans == rocblas_operation_none op( A ) = A^H, op( B ) = B^H, and A and B are k by n if trans == rocblas_operation_conjugate_transpose
- Parameters
-
[in] handle [rocblas_handle] handle to the rocblas library context queue. [in] uplo [rocblas_fill] rocblas_fill_upper: C is an upper triangular matrix rocblas_fill_lower: C is a lower triangular matrix [in] trans [rocblas_operation] rocblas_operation_conjugate_transpose: op( A ) = A^H, op( B ) = B^H rocblas_operation_none: op( A ) = A, op( B ) = B [in] n [rocblas_int] n specifies the number of rows and columns of C. n >= 0. [in] k [rocblas_int] k specifies the number of columns of op(A). k >= 0. [in] alpha alpha specifies the scalar alpha. When alpha is zero then A is not referenced and A need not be set before entry. [in] A pointer storing matrix A on the GPU. Martrix dimension is ( lda, k ) when if trans = rocblas_operation_none, otherwise (lda, n) only the upper/lower triangular part is accessed. [in] lda [rocblas_int] lda specifies the first dimension of A. if trans = rocblas_operation_none, lda >= max( 1, n ), otherwise lda >= max( 1, k ). [in] B pointer storing matrix B on the GPU. Martrix dimension is ( ldb, k ) when if trans = rocblas_operation_none, otherwise (ldb, n) only the upper/lower triangular part is accessed. [in] ldb [rocblas_int] ldb specifies the first dimension of B. if trans = rocblas_operation_none, ldb >= max( 1, n ), otherwise ldb >= max( 1, k ). [in] beta beta specifies the scalar beta. When beta is zero then C need not be set before entry. [in] C pointer storing matrix C on the GPU. The imaginary component of the diagonal elements are not used but are set to zero unless quick return. [in] ldc [rocblas_int] ldc specifies the first dimension of C. ldc >= max( 1, n ).
