| integer(kind(hipblas_status_success)) function | hipblasrotstridedbatchedex_ (handle, n, x, xtype, incx, stridex, y, ytype, incy, stridey, c, s, cstype, batchcount, executiontype) |
Detailed Description
BLAS EX API.
The rotStridedBatchedEx functions apply the Givens rotation matrix defined by c=cos(alpha) and s=sin(alpha) to strided batched vectors x_i and y_i, for i = 1, ..., batchCount. Scalars c and s can be stored in either host or device memory. The location is specified by calling hipblasSetPointerMode.
If cs_type is real:
x := c * x + s * y y := c * y - s * x
If cs_type is complex, the imaginary part of c is ignored:
x := real(c) * x + s * y y := real(c) * y - conj(s) * x
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 and y_i vectors. [in,out] x - device pointer to the first vector x_1. [in] xType [hipDataType] specifies the datatype of each vector x_i. [in] incx - [int] specifies the increment between elements of each x_i. [in] stridex - [hipblasStride] specifies the increment from the beginning of x_i to the beginning of x_(i+1). [in,out] y - device pointer to the first vector y_1. [in] yType [hipDataType] specifies the datatype of each vector y_i. [in] incy - [int] specifies the increment between elements of each y_i. [in] stridey - [hipblasStride] specifies the increment from the beginning of y_i to the beginning of y_(i+1). [in] c - device pointer or host pointer to scalar cosine component of the rotation matrix. [in] s - device pointer or host pointer to scalar sine component of the rotation matrix. [in] csType [hipDataType] specifies the datatype of c and s. [in] batchCount - [int] the number of x and y arrays, that is, the number of batches. [in] executionType [hipDataType] specifies the datatype of computation.
