Detailed Description

BLAS Level 1 API.

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_i**H*x_i ) for complex vectors x, for i = 1, ..., batch_count
Parameters
[in]handle[rocblas_handle] handle to the rocblas library context queue.
[in]n[rocblas_int] number of elements in each x_i.
[in]xdevice array of device pointers storing each vector x_i.
[in]incx[rocblas_int] specifies the increment for the elements of each x_i. incx must be > 0.
[in]batch_count[rocblas_int] number of instances in the batch
[out]resultsdevice 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.
