Detailed Description
BLAS Level 1 API.
rotmBatched applies the modified Givens rotation matrix defined by param_i to batched vectors x_i and y_i, for i = 1, ..., batchCount.
- Parameters
-
[in] handle [hipblasHandle_t] handle to the hipblas library context queue. [in] n [int] number of elements in the x and y vectors. [in,out] x device array of device pointers storing each vector x_i. [in] incx [int] specifies the increment between elements of each x_i. [in,out] y device array of device pointers storing each vector y_1. [in] incy [int] specifies the increment between elements of each y_i. [in] param device array of device vectors of 5 elements defining the rotation. param[0] = flag param[1] = H11 param[2] = H21 param[3] = H12 param[4] = H22 The flag parameter defines the form of H: flag = -1 => H = ( H11 H12 H21 H22 ) flag = 0 => H = ( 1.0 H12 H21 1.0 ) flag = 1 => H = ( H11 1.0 -1.0 H22 ) flag = -2 => H = ( 1.0 0.0 0.0 1.0 ) param may ONLY be stored on the device for the batched version of this function. [in] batchCount [int] the number of x and y arrays, i.e. the number of batches.
