Detailed Description

BLAS EX API

\details
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      |
    | f64_r  | f64_r  |    f64_r    |     f64_r      |
    | f32_c  | f32_c  |    f32_c    |     f32_c      |
    | f64_c  | f64_c  |    f64_c    |     f64_c      |

@param[in]
handle    [rocblas_handle]
          handle to the rocblas library context queue.
@param[in]
n         [rocblas_int]
          the number of elements in x and y.
@param[in]
x         device pointer storing vector x.
@param[in]
x_type [rocblas_datatype]
       specifies the datatype of vector x.
@param[in]
incx      [rocblas_int]
          specifies the increment for the elements of y.
@param[in]
y         device pointer storing vector y.
@param[in]
y_type [rocblas_datatype]
      specifies the datatype of vector y.
@param[in]
incy      [rocblas_int]
