Detailed Description
BLAS Level 2 API.
her2_batched performs the matrix-vector operations
A_i := A_i + alpha*x_i*y_i**H + conj(alpha)*y_i*x_i**H
where alpha is a complex scalar, x_i and y_i are vectors, and A_i is an n by n Hermitian matrix for each batch in i = [1, batch_count].
- Parameters
-
[in] handle [rocblas_handle] handle to the rocblas library context queue. [in] uplo [rocblas_fill] specifies whether the upper 'rocblas_fill_upper' or lower 'rocblas_fill_lower' rocblas_fill_upper: The upper triangular part of each A_i is supplied. rocblas_fill_lower: The lower triangular part of each A_i is supplied. [in] n [rocblas_int] the number of rows and columns of each matrix A_i, must be at least 0. [in] alpha device pointer or host pointer to scalar alpha. [in] x device array of device pointers storing each vector x_i. [in] incx [rocblas_int] specifies the increment for the elements of x. [in] y device array of device pointers storing each vector y_i. [in] incy [rocblas_int] specifies the increment for the elements of each y_i. [in,out] A device array of device pointers storing the specified triangular portion of each Hermitian matrix A_i of size (lda, n). if uplo == rocblas_fill_upper: The upper triangular portion of each Hermitian matrix A_i is supplied. The lower triangular portion of each A_i will not be touched. if uplo == rocblas_fill_lower: The lower triangular portion of each Hermitian matrix A_i is supplied. The upper triangular portion of each A_i will not be touched. Note that the imaginary part of the diagonal elements are not accessed and are assumed to be 0. [in] lda [rocblas_int] specifies the leading dimension of each A_i. Must be at least max(lda, 1). [in] batch_count [rocblas_int] number of instances in the batch.
