| integer(kind(hipblas_status_success)) function | hipblasnrm2batchedex_ (handle, n, x, xtype, incx, batchcount, myresult, resulttype, executiontype) |
Detailed Description
BLAS EX API.
The nrm2BatchedEx 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, ..., batchCount
result := sqrt( x_i**H*x_i ) for complex vectors x, for i = 1, ..., batchCount
The supported types are determined by the backend. See the rocBLAS or cuBLAS documentation.
- 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 array of device pointers storing each vector x_i. [in] xType [hipDataType] specifies the datatype of each vector x_i. [in] incx - [int] specifies the increment for the elements of each x_i. incx must be > 0. [in] batchCount - [int] number of instances in the batch. [out] myResult device pointer or host pointer to array of batchCount size for nrm2 results. Returns 0.0 for each element if n <= 0, incx<=0. [in] resultType [hipDataType] specifies the datatype of the result. [in] executionType [hipDataType] specifies the datatype of computation.
