Detailed Description

!

BLAS Level 1 API

\details
nrm2_batched computes the euclidean norm over a batch of real or complex vectors

          result := sqrt( x_i'x_i ) for real vectors x, for i = 1, ..., batch_count
          result := sqrt( x_iHx_i ) for complex vectors x, for i = 1, ..., batch_count

@param[in]
handle    [rocblas_handle]
          handle to the rocblas library context queue.
@param[in]
n         [rocblas_int]
          number of elements in each x_i.
@param[in]
x         device array of device pointers storing each vector x_i.
@param[in]
incx      [rocblas_int]
          specifies the increment for the elements of each x_i. incx must be > 0.
@param[in]
batch_count [rocblas_int]
          number of instances in the batch
@param[out]
results
          device pointer or host pointer to array of batch_count size for nrm2 results.
          return is 0.0 for each element if n <= 0, incx<=0.
