Detailed Description

BLAS Level 1 API.

The nrm2StridedBatched functions compute 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

• Supported precisions in rocBLAS : s, d, c, z, sc, and dz.
• Supported precisions in cuBLAS : No support.

Parameters

[in]	handle	- [hipblasHandle_t] handle to the hipBLAS library context queue.
[in]	n	- [int] number of elements in each x_i.
[in]	x	- device 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) to the next one (x_i+1). There are no restrictions placed on stridex. However, the user should ensure that stridex is of an appropriate size. For a typical case, this means stridex >= n * incx.
[in]	batchCount	- [int] number of instances in the batch.
[out]	myResult	device pointer or host pointer to array for storing contiguous batchCount results. Return value is 0.0 for each element if n <= 0, incx<=0.
