| integer(kind(hipblas_status_success)) function | hipblasdotstridedbatchedex_ (handle, n, x, xtype, incx, stridex, y, ytype, incy, stridey, batchcount, myresult, resulttype, executiontype) |
Detailed Description
BLAS EX API.
The dotStridedBatchedEx functions perform a batch of dot products of vectors x and y:
result_i = x_i * y_i;
The dotc_strided_batched_ex functions 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 and x_i and y_i are vectors, for i = 1, ..., batchCount.
The supported types are determined by the backend. See rocBLAS/cuBLAS documentation.
- 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] xType [hipDataType] specifies the datatype of each vector x_i. [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] yType [hipDataType] specifies the datatype of each vector y_i. [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] myResult device array or host array of batchCount size to store the dot products of each batch. Returns 0.0 for each element if n <= 0. [in] resultType [hipDataType] specifies the datatype of the result. [in] executionType [hipDataType] specifies the datatype of computation.
