Detailed Description

BLAS Level 1 API.

nrm2 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

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]	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.
