integer(kind(hipblas_status_success)) function hipblashdotstridedbatched_ (handle, n, x, incx, stridex, y, incy, stridey, batchcount, myresult)
 

Detailed Description

BLAS Level 1 API.

The dot(u)StridedBatched functions perform a batch of dot products of vectors x and y. 

result_i = x_i * y_i;

The dotcStridedBatched functions perform 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 and x_i and y_i are vectors, for i = 1, ..., batchCount.

  • Supported precisions in rocBLAS : h, bf, s, d, c, and z.
  • Supported precisions in cuBLAS : No support.
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]x- device 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) to the next one (x_i+1).
[in]y- device 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) to the next one (y_i+1).
[in]batchCount- [int] number of instances in the batch.
[in,out]myResultdevice array or host array of batchCount size to store the dot products of each batch. Returns 0.0 for each element if n <= 0.
