Detailed Description
BLAS Level 2 API.
spmvStridedBatched 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 should contain an upper or lower triangular n by n packed symmetric matrix.
- 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] alpha device pointer or host pointer to scalar alpha [in] A Device pointer to the first matrix A_1 on the GPU [in] strideA [hipblasStride] stride from the start of one matrix (A_i) and the next one (A_i+1) [in] x Device pointer to the first vector x_1 on the GPU [in] incx [int] specifies the increment for the elements of each vector x_i [in] stridex [hipblasStride] stride from the start of one vector (x_i) and the next one (x_i+1). There are no restrictions placed on stridex, however the user should take care to ensure that stridex is of appropriate size. This typically means stridex >= n * incx. stridex should be non zero. [in] beta device pointer or host pointer to scalar beta [out] y Device pointer to the first vector y_1 on the GPU [in] incy [int] specifies the increment for the elements of each vector y_i [in] stridey [hipblasStride] stride from the start of one vector (y_i) and the next one (y_i+1). There are no restrictions placed on stridey, however the user should take care to ensure that stridey is of appropriate size. This typically means stridey >= n * incy. stridey should be non zero. [in] batchCount [int] number of instances in the batch
