Matlab offers many facilities for problem solving. The following solutions are provided to questions that do not provide complete Matlab code. They are mainly intended to demonstrate features mentioned in the book.

  Matlab中如何求一个序列的极值？在Matlab中有专门求序列最大值和最小值的函数，分别是Max  和  Min，但是有时候我们不满足于求整个序列的最值，而是对序列的极值，也就是局部的最值感兴趣。对于解析函 数，这个比较简单，只要令一阶倒数为零求出对应的自变量就行了。(Matlab how to seek a extremum sequence? In the Matlab there is a special function for sequence of maximum and minimum values, respectively is Max and Min the value, but sometimes we do not meet for the whole series, but the extremum sequence, also is the value of local interest. For analytic functions, this is relatively simple, as long as the countdown to zero order and related variables on the line.)
