Detailed Description
BLAS Level 3 API.
syrkxBatched performs a batch of the matrix-matrix operations for a symmetric rank-k update
C_i := alpha*op( A_i )*op( B_i )^T + beta*C_i
where alpha and beta are scalars, op(A_i) and op(B_i) are n by k matrix, and C_i is a symmetric n x n matrix stored as either upper or lower. This routine should only be used when the caller can guarantee that the result of op( A_i )*op( B_i )^T will be symmetric.
op( A_i ) = A_i, op( B_i ) = B_i, and A_i and B_i are n by k if trans == HIPBLAS_OP_N op( A_i ) = A_i^T, op( B_i ) = B_i^T, and A_i and B_i are k by n if trans == HIPBLAS_OP_T
- Parameters
-
[in] handle [hipblasHandle_t] handle to the hipblas library context queue. [in] uplo [hipblasFillMode_t] HIPBLAS_FILL_MODE_UPPER: C_i is an upper triangular matrix HIPBLAS_FILL_MODE_LOWER: C_i is a lower triangular matrix [in] trans [hipblasOperation_t] HIPBLAS_OP_T: op( A_i ) = A_i^T, op( B_i ) = B_i^T HIPBLAS_OP_N: op( A_i ) = A_i, op( B_i ) = B_i [in] n [int] n specifies the number of rows and columns of C_i. n >= 0. [in] k [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 device array of device pointers storing each matrix_i A of dimension (lda, k) when trans is HIPBLAS_OP_N, otherwise of dimension (lda, n) [in] lda [int] lda specifies the first dimension of A_i. if trans = HIPBLAS_OP_N, lda >= max( 1, n ), otherwise lda >= max( 1, k ). [in] B device array of device pointers storing each matrix_i B of dimension (ldb, k) when trans is HIPBLAS_OP_N, otherwise of dimension (ldb, n) [in] ldb [int] ldb specifies the first dimension of B. if trans = HIPBLAS_OP_N, 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 device array of device pointers storing each matrix C_i on the GPU. [in] ldc [int] ldc specifies the first dimension of C. ldc >= max( 1, n ). [in] batchCount [int] number of instances in the batch.
