Detailed Description

BLAS Level 1 API.

rotmStridedBatched applies the modified Givens rotation matrix defined by param_i to strided 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]xdevice pointer pointing to first strided batched vector x_1.
[in]incx[int] specifies the increment between elements of each x_i.
[in]stride_x[hipblasStride] specifies the increment between the beginning of x_i and x_(i + 1)
[in,out]ydevice pointer pointing to first strided batched vector y_1.
[in]incy[int] specifies the increment between elements of each y_i.
[in]stridey[hipblasStride] specifies the increment between the beginning of y_i and y_(i + 1)
[in]paramdevice pointer pointing to first array of 5 elements defining the rotation (param_1). 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 strided_batched version of this function.
[in]strideParam[hipblasStride] specifies the increment between the beginning of param_i and param_(i + 1)
[in]batchCount[int] the number of x and y arrays, i.e. the number of batches.
