摘要: For many problems of Numerical Analysis the derivatives some functions need to be computed. In practice, programs for computing may (1) hand-coded, (2) generated by symbolic manipulation formulas, (3) set up via function calls and divided differences, or (4) obtained using automatic differentiation. Numerically, differences approach is still standard technique. But in cases, can cheaper more accurately this paper we are concerned mainly with demonstrating key idea
