Detailed Description

BLAS Level 1 API.

dotStridedBatched(u) performs a batch of dot products of vectors x and y

result_i = x_i * y_i;

dotcStridedBatched performs a batch of dot products of the conjugate of complex vector x and complex vector y

result_i = conjugate (x_i) * y_i;

where (x_i, y_i) is the i-th instance of the batch. x_i and y_i are vectors, for i = 1, ..., batchCount

Parameters
[in]handle[hipblasHandle_t] handle to the hipblas library context queue.
[in]n[int] the number of elements in each x_i and y_i.
[in]xdevice pointer to the first vector (x_1) in the batch.
[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]ydevice pointer to the first vector (y_1) in the batch.
[in]incy[int] specifies the increment for the elements of each y_i.
[in]stridey[hipblasStride] stride from the start of one vector (y_i) and the next one (y_i+1)
[in]batchCount[int] number of instances in the batch
[in,out]resultdevice array or host array of batchCount size to store the dot products of each batch. return 0.0 for each element if n <= 0.
