integer(kind(rocblas_status_success)) function rocblas_dot_ex_ (handle, n, x, x_type, incx, y, y_type, incy, myresult, result_type, execution_type)
 

Detailed Description

BLAS EX API.

dot_ex performs the dot product of vectors x and y.

result = x * y;

dotc_ex performs the dot product of the conjugate of complex vector x and complex vector y

result = conjugate (x) * y;

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 x and y.
[in]x- device pointer storing vector x.
[in]x_type- [rocblas_datatype] specifies the datatype of vector x.
[in]incx- [rocblas_int] specifies the increment for the elements of y.
[in]y- device pointer storing vector y.
[in]y_type- [rocblas_datatype] specifies the datatype of vector y.
[in]incy- [rocblas_int] specifies the increment for the elements of y.
[in,out]myResultdevice pointer or host pointer to store the dot product. Return value is 0.0 if n <= 0.
[in]result_type- [rocblas_datatype] specifies the datatype of the result.
[in]execution_type- [rocblas_datatype] specifies the datatype of computation.
