Detailed Description

BLAS Level 1 API.

nrm2_strided_batched computes the euclidean norm over a batch of real or complex vectors

      := sqrt( x_i'*x_i ) for real vectors x, for i = 1, ..., batch_count
      := sqrt( x_i**H*x_i ) for complex vectors, 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]	x	device pointer to the first vector x_1.
[in]	incx	[rocblas_int] specifies the increment for the elements of each x_i. incx must be > 0.
[in]	stridex	[rocblas_stride] 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]	batch_count	[rocblas_int] number of instances in the batch
[out]	results	device pointer or host pointer to array for storing contiguous batch_count results. return is 0.0 for each element if n <= 0, incx<=0.
