Detailed Description

BLAS Level 1 API.

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

result_i = x_i * y_i;

dotc_strided_batched 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, ..., batch_count

Parameters

[in]	handle	[rocblas_handle] handle to the rocblas library context queue.
[in]	n	[rocblas_int] the number of elements in each x_i and y_i.
[in]	x	device pointer to the first vector (x_1) in the batch.
[in]	incx	[rocblas_int] specifies the increment for the elements of each x_i.
[in]	stridex	[rocblas_stride] stride from the start of one vector (x_i) and the next one (x_i+1)
[in]	y	device pointer to the first vector (y_1) in the batch.
[in]	incy	[rocblas_int] specifies the increment for the elements of each y_i.
[in]	stridey	[rocblas_stride] stride from the start of one vector (y_i) and the next one (y_i+1)
[in]	batch_count	[rocblas_int] number of instances in the batch
[in,out]	result	device array or host array of batch_count size to store the dot products of each batch. return 0.0 for each element if n <= 0.
