1. 如果matlab有两个函数nargin和nargout，分别返回matlab函数的输入和输出参数的个数。如果采用元组变量varargin和varargout来替代常规的输入和输出参数，则函数就可以接收数目可变的输入和输出参数。-1. If there are two matlab functions nargin and nargout, respectively matlab function back to the input and output parameters of the

function [out1,out2] = humps(x) HUMPS A function used by QUADDEMO, ZERODEMO and FPLOTDEMO. Y = HUMPS(X) is a function with strong maxima near x = .3 and x = .9. [X,Y] = HUMPS(X) also returns X. With no input arguments, HUMPS uses X
