Detailed Description

BLAS Level 1 API.

nrm2StridedBatched computes the euclidean norm over a batch of real or complex vectors

      := sqrt( x_i'*x_i ) for real vectors x, for i = 1, ..., batchCount
      := sqrt( x_i**H*x_i ) for complex vectors, for i = 1, ..., batchCount
Parameters
[in]handle[hipblasHandle_t] handle to the hipblas library context queue.
[in]n[int] number of elements in each x_i.
[in]xdevice pointer to the first vector x_1.
[in]incx[int] specifies the increment for the elements of each x_i. incx must be > 0.
[in]stridex[hipblasStride] stride from the start of one vector (x_i) and the next one (x_i+1). There are no restrictions placed on stride_x, however the user should take care to ensure that stride_x is of appropriate size, for a typical case this means stride_x >= n * incx.
[in]batchCount[int] number of instances in the batch
[out]resultdevice pointer or host pointer to array for storing contiguous batch_count results. return is 0.0 for each element if n <= 0, incx<=0.
