ARGUMENTSx, y, magnitude
FUNCTIONmagnitude
RETURN TYPEvoid
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Calculates the magnitude of 2D vectors.

The function cv::magnitude calculates the magnitude of 2D vectors formed from the corresponding elements of x and y arrays:

\texttt{dst} (I) =  \sqrt{\texttt{x}(I)^2 + \texttt{y}(I)^2}

See: cartToPolar, polarToCart, phase, sqrt

magnitude(x: Mat, y: Mat, magnitude: Mat): void;
x

floating-point array of x-coordinates of the vectors.

y

floating-point array of y-coordinates of the vectors; it must have the same size as x.

magnitude

Output destination, filled by the native operation. output array of the same size and type as x.
