Comparison of computational complexity (I): (a) number of multiplications; (b) number of additions. Four curves in (a) show the maximum and minimum multiplication requirements for the component-wise recursion method and the direct transformation method for a required Zernike component at one (x, y) position; the same applies to four curves in (b) for addition operations.
