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

export function getNextMatrix(
    offsetMatrix: number[],
    targetMatrix: number[],
    origin: number[],
    n: number,
) {
    return multiply(
        offsetMatrix,
        getAbsoluteMatrix(targetMatrix, n, origin),
        n,
    );
}
export function scaleMatrix(

if (length - 1 === i) {
            offsetMatrix = mat.slice();
        }

        if (isObject(matrix[n - 1])) {
            [matrix[n - 1], matrix[2 * n - 1]] =
                getSVGOffset(
                    matrix[n - 1] as any,
                    endContainer,
                    n,
                    matrix[2 * n - 1] as any,
                    mat,
                    matrixes[i + 1],
                );
        }
        mat = multiply(
            mat,
            matrix,
            n,
        );
    });
    const isMatrix3d = !isSVGGraphicElement && is3d;
