How to use the @moveable/matrix.getOrigin function in @moveable/matrix

[
            [left, top, right, bottom],
            origin,
            pos1,
            pos2,
            pos3,
            pos4,
            direction,
        ] = caculateMoveablePosition(matrix, transformOrigin, width, height);

        const n = is3d ? 4 : 3;
        let beforePos = [0, 0];

        [
            beforePos, beforeOrigin, , , , , beforeDirection,
        ] = caculateMoveablePosition(offsetMatrix, plus(transformOrigin, getOrigin(targetMatrix, n)), width, height);

        beforeOrigin = [
            beforeOrigin[0] + beforePos[0] - left,
            beforeOrigin[1] + beforePos[1] - top,
        ];

        clientRect = getClientRect(target);
        containerRect = getClientRect(
            getOffsetInfo(parentContainer, parentContainer, true).offsetParent || document.body,
        );
        rotation = getRotationRad([pos1, pos2], direction);
    }

    return {
        rotation,
        containerRect,
