Detailed Description

BLAS Level 2 API.

syr2StridedBatched the matrix-vector operations

A[i] := A[i] + alpha*x[i]*y[i]**T + alpha*y[i]*x[i]**T

where alpha is a scalar, x[i] and y[i] are vectors, and A[i] is a n by n symmetric matrices, 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' if HIPBLAS_FILL_MODE_UPPER, the lower part of A is not referenced if HIPBLAS_FILL_MODE_LOWER, the upper part of A is not referenced
[in]n[int] the number of rows and columns of each matrix A.
[in]alphadevice pointer or host pointer to scalar alpha.
[in]xdevice pointer to the first vector x_1.
[in]incx[int] specifies the increment for the elements of each x_i.
[in]stridex[hipblasStride] specifies the pointer increment between vectors (x_i) and (x_i+1).
[in]ydevice pointer to the first vector y_1.
[in]incy[int] specifies the increment for the elements of each y_i.
[in]stridey[hipblasStride] specifies the pointer increment between vectors (y_i) and (y_i+1).
[in,out]Adevice pointer to the first matrix A_1.
[in]lda[int] specifies the leading dimension of each A_i.
[in]strideA[hipblasStride] stride from the start of one matrix (A_i) and the next one (A_i+1)
[in]batchCount[int] number of instances in the batch
