Detailed Description
BLAS Level 3 API.
The syrk functions perform one of the matrix-matrix operations for a symmetric rank-k update:
C := alpha*op( A )*op( A )^T + beta*C,
where alpha and beta are scalars, op(A) is an n by k matrix, and C is a symmetric n x n matrix stored as either upper or lower.
op( A ) = A, and A is n by k if transA == rocblas_operation_none op( A ) = A^T and A is k by n if transA == rocblas_operation_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] transA - [rocblas_operation] - rocblas_operation_transpose: op(A) = A^T
- rocblas_operation_none: op(A) = A
- rocblas_operation_conjugate_transpose: op(A) = A^T
- rocblas_operation_conjugate_transpose is not supported for complex types. See cherk and zherk.
[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, A is not referenced and A need not be set before entry. [in] A - pointer storing matrix A on the GPU. Matrix dimension is ( lda, k ) if transA = rocblas_operation_none. Otherwise, (lda, n). [in] lda - [rocblas_int] lda specifies the first dimension of A. - If transA = rocblas_operation_none, lda >= max( 1, n ).
- Otherwise, lda >= 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. Only the upper/lower triangular part is accessed. [in] ldc - [rocblas_int] ldc specifies the first dimension of C. ldc >= max( 1, n ).
