Detailed Description

BLAS Level 3 API

\details

herk_batched performs a batch of the matrix-matrix operations for a Hermitian rank-k update

C_i := alphaop( A_i )op( A_i )^H + betaC_i

where  alpha and beta are scalars, op(A) is an n by k matrix, and
C_i is a n x n Hermitian 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^H and A_i is k by n if transA == rocblas_operation_conjugate_transpose

@param[in]
handle    [rocblas_handle]
          handle to the rocblas library context queue.

@param[in]
uplo    [rocblas_fill]
        rocblas_fill_upper:  C_i is an upper triangular matrix
        rocblas_fill_lower:  C_i is a  lower triangular matrix

@param[in]
transA  [rocblas_operation]
        rocblas_operation_conjugate_transpose: op(A) = A^H
        rocblas_operation_none:                op(A) = A

@param[in]
n       [rocblas_int]
        n specifies the number of rows and columns of C_i. n >= 0.

@param[in]
k       [rocblas_int]
        k specifies the number of columns of op(A). k >= 0.

@param[in]
alpha
        alpha specifies the scalar alpha. When alpha is
        zero then A is not referenced and A need not be set before
        entry.

@param[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)

@param[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 ).

@param[in]
beta
        beta specifies the scalar beta. When beta is
        zero then C need not be set before entry.

@param[in]
C       device array of device pointers storing each matrix C_i on the GPU.
        The imaginary component of the diagonal elements are not used but are set to zero unless quick return.

@param[in]
ldc    [rocblas_int]
       ldc specifies the first dimension of C. ldc >= max( 1, n ).
@param[in]
batch_count [rocblas_int]
            number of instances in the batch.
