Detailed Description
BLAS Level 2 API.
herStridedBatched performs the matrix-vector operations
A_i := A_i + alpha*x_i*x_i**H
where alpha is a real scalar, x_i is a vector, and A_i is an n by n Hermitian matrix, for i = 1, ..., batchCount.
- Parameters
-
[in] handle [hipblasHandle_t] handle to the hipblas library context queue. [in] uplo [hipblasFillMode_t] specifies whether the upper 'HIPBLAS_FILL_MODE_UPPER' or lower 'HIPBLAS_FILL_MODE_LOWER' HIPBLAS_FILL_MODE_UPPER: The upper triangular part of each A_i is supplied in A. HIPBLAS_FILL_MODE_LOWER: The lower triangular part of each A_i is supplied in A. [in] n [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 pointer pointing to the first vector (x_1). [in] incx [int] specifies the increment for the elements of each x_i. [in] stridex [hipblasStride] stride from the start of one vector (x_i) and the next one (x_i+1). [in,out] A device array of device pointers storing the specified triangular portion of each Hermitian matrix A_i. Points to the first matrix (A_1). if uplo == HIPBLAS_FILL_MODE_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 == HIPBLAS_FILL_MODE_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 [int] specifies the leading dimension of each A_i. [in] strideA [hipblasStride] stride from the start of one (A_i) and the next (A_i+1) [in] batchCount [int] number of instances in the batch.
