| 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] myResult device 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.
