Detailed Description

BLAS Level 2 API.

symvBatched performs the matrix-vector operation:

y_i := alpha*A_i*x_i + beta*y_i,

where (A_i, x_i, y_i) is the i-th instance of the batch. alpha and beta are scalars, x_i and y_i are vectors and A_i is an n by n symmetric matrix, for i = 1, ..., batchCount. A a should contain an upper or lower triangular symmetric matrix and the opposing triangular part of A is not referenced

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] number of rows and columns of each matrix A_i
[in]alphadevice pointer or host pointer to scalar alpha
[in]Adevice array of device pointers storing each matrix A_i
[in]lda[int] specifies the leading dimension of each matrix A_i
[in]xdevice array of device pointers storing each vector x_i
[in]incx[int] specifies the increment for the elements of each vector x_i
[in]betadevice pointer or host pointer to scalar beta
[out]ydevice array of device pointers storing each vector y_i
[in]incy[int] specifies the increment for the elements of each vector y_i
[in]batchCount[int] number of instances in the batch
