integer(kind(rocblas_status_success)) function	rocblas_dot_batched_ex_ (handle, n, x, x_type, incx, y, y_type, incy, batch_count, myResult, result_type, execution_type)

Detailed Description

BLAS EX API.

dot_batched_ex performs a batch of dot products of vectors x and y

result_i = x_i * y_i;

dotc_batched_ex 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

Currently supported datatypes are as follows:

--------------------------------------------------
| x_type | y_type | result_type | execution_type |
|--------|--------|-------------|----------------|
| f16_r  | f16_r  |    f16_r    |     f16_r      |
| f16_r  | f16_r  |    f16_r    |     f32_r      |
| bf16_r | bf16_r |    bf16_r   |     f32_r      |
| f32_r  | f32_r  |    f32_r    |     f32_r      |
| f64_r  | f64_r  |    f64_r    |     f64_r      |
| f32_c  | f32_c  |    f32_c    |     f32_c      |
| f64_c  | f64_c  |    f64_c    |     f64_c      |
--------------------------------------------------

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 array of device pointers storing each vector x_i.
[in]	x_type	[rocblas_datatype] specifies the datatype of each vector x_i.
[in]	incx	[rocblas_int] specifies the increment for the elements of each x_i.
[in]	y	device array of device pointers storing each vector y_i.
[in]	y_type	[rocblas_datatype] specifies the datatype of each vector y_i.
[in]	incy	[rocblas_int] specifies the increment for the elements of each y_i.
[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.
[in]	result_type	[rocblas_datatype] specifies the datatype of the result.
[in]	execution_type	[rocblas_datatype] specifies the datatype of computation.
