integer(kind(rocblas_status_success)) function rocblas_dotc_strided_batched_ex_ (handle, n, x, x_type, incx, stride_x, y, y_type, incy, stride_y, batch_count, myresult, result_type, execution_type)
 

Detailed Description

BLAS EX API.

The dotc_strided_batched_ex 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. 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
f32_r f32_r f64_r f64_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 pointer to the first vector (x_1) in the batch.
[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]stride_x- [rocblas_stride] 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]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]stride_y- [rocblas_stride] stride from the start of one vector (y_i) to the next one (y_i+1).
[in]batch_count- [rocblas_int] number of instances in the batch.
[in,out]myResultdevice array or host array of batch_count size to store the dot products of each batch. Returns 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.
