| integer(kind(rocblas_status_success)) function | rocblas_nrm2_strided_batched_ex_ (handle, n, x, x_type, incx, stride_x, batch_count, results, result_type, execution_type) |
Detailed Description
BLAS_EX API.
The nrm2_strided_batched_ex functions compute 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, for i = 1, ..., batch_count
Currently supported datatypes are as follows:
| x_type | result | execution_type |
|---|---|---|
| bf16_r | bf16_r | f32_r |
| f16_r | f16_r | f32_r |
| f32_r | f32_r | f32_r |
| f64_r | f64_r | f64_r |
| f32_c | f32_r | f32_r |
| f64_c | f64_r | f64_r |
- 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] x_type - [rocblas_datatype] specifies the datatype of each vector x_i. [in] incx - [rocblas_int] specifies the increment for the elements of each x_i. incx must be > 0. [in] stride_x - [rocblas_stride] stride from the start of one vector (x_i) to the next one (x_i+1). There are no restrictions placed on stride_x. However, ensure that stride_x is of an 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. Returns 0.0 for each element if n <= 0, incx<=0. [in] result_type - [rocblas_datatype] specifies the datatype of the result. [in] execution_type - [rocblas_datatype] specifies the datatype of computation.
