matlab实现牛顿插值，一个简单的程序(matlab implementation of Newton interpolation, a simple procedure)

This tutorial white-paper illustrates practical aspects of FIR filter design and fixed-point implementation along with the algorithms available in the Filter Design Toolbox and the Signal Processing Toolbox for this purpose. The emphasis is mostly on lowpass filters, but many of the results apply to other filter types as well. The tutorial focuses on practical aspects of filter design and implementation, and on the advantages and disadvantages of the different design algorithms. The theory behind the design algorithms is avoided except when needed to motivate them.

在做复合形法优化时，用到《精通MATLAB最优化设计》一书中的复合形法程序，发现做其他例题时运行不了。去掉bug后，改进如下，如果你遇到同样问题，不妨下来试试。如果你没有Funval.m，可以将程序中的Funval函数换成subs(In doing complex method optimization, use the " Mastering MATLAB Optimization Design," a book of complex method program, found other examples can not do when running. After removing the bug, improvements are as follows, if you encounter the same problem, we might try it. If you do not Funval.m, the program can be replaced by a function of Funval subs)
