[−][src]Function opencv::core::scale_add
pub fn scale_add(
src1: &dyn ToInputArray,
alpha: f64,
src2: &dyn ToInputArray,
dst: &mut dyn ToOutputArray
) -> Result<()>
Calculates the sum of a scaled array and another array.
The function scaleAdd is one of the classical primitive linear algebra operations, known as DAXPY or SAXPY in BLAS. It calculates the sum of a scaled array and another array: The function can also be emulated with a matrix expression, for example:
ⓘ
Mat A(3, 3, CV_64F); ... A.row(0) = A.row(1)*2 + A.row(2);
Parameters
- src1: first input array.
- alpha: scale factor for the first array.
- src2: second input array of the same size and type as src1.
- dst: output array of the same size and type as src1.
