BLAS Level 3 API.

syrk_batched performs a batch of the matrix-matrix operations for a symmetric rank-k update

C_i := alpha*op( A_i )*op( A_i )^T + beta*C_i

where alpha and beta are scalars, op(A_i) is an n by k matrix, and C_i is a symmetric n x n matrix stored as either upper or lower.

op( A_i ) = A_i, and A_i is n by k if transA == rocblas_operation_none
op( A_i ) = A_i^T and A_i 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_i is an upper triangular matrix rocblas_fill_lower: C_i 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.

Parameters

[in]	n	[rocblas_int] n specifies the number of rows and columns of C_i. 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	device array of device pointers storing each matrix_i A of dimension (lda, k) when transA is rocblas_operation_none, otherwise of dimension (lda, n)
[in]	lda	[rocblas_int] lda specifies the first dimension of A_i. 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	device array of device pointers storing each matrix C_i on the GPU.
[in]	ldc	[rocblas_int] ldc specifies the first dimension of C. ldc >= max( 1, n ).
[in]	batch_count	[rocblas_int] number of instances in the batch.
