integer(kind(rocblas_status_success)) function | rocblas_nrm2_ex_ (handle, n, x, x_type, incx, results, result_type, execution_type) |
Detailed Description
BLAS_EX API.
nrm2_ex computes the euclidean norm of a real or complex vector
result := sqrt( x'*x ) for real vectors result := sqrt( x**H*x ) for complex vectors
Currently supported datatypes are as follows:
x_type | result | execution_type |
---|---|---|
f16_r | f16_r | f32_r |
f32_r | f32_r | f32_r |
f64_r | f64_r | f64_r |
f32_c | f32_r | f32_r |
f64_c | f64_r | f64_r |
- Parameters
-
[in] handle [rocblas_handle] handle to the rocblas library context queue. [in] n [rocblas_int] the number of elements in x. [in] x device pointer storing vector x. [in] x_type [rocblas_datatype] specifies the datatype of the vector x. [in] incx [rocblas_int] specifies the increment for the elements of y. [in,out] result device pointer or host pointer to store the nrm2 product. return is 0.0 if n, incx<=0. [in] result_type [rocblas_datatype] specifies the datatype of the result. [in] execution_type [rocblas_datatype] specifies the datatype of computation.
