Detailed Description

BLAS Level 1 API.

scal_batched scales each element of vector x_i with scalar alpha, for i = 1, ... , batch_count.

 x_i := alpha * x_i

where (x_i) is the i-th instance of the batch.

Parameters
[in]handle[rocblas_handle] handle to the rocblas library context queue.
[in]n[rocblas_int] the number of elements in each x_i.
[in]alphahost pointer or device pointer for the scalar alpha.
[in,out]xdevice array of device pointers storing each vector x_i.
[in]incx[rocblas_int] specifies the increment for the elements of each x_i.
[in]batch_count[rocblas_int] specifies the number of batches in x.
