nonlinear-solve

经典的功率谱和 双谱估计，很好，看看能用上的。(Classic power spectrum and dual spectrum estimation, well, look at can be used on.)

这是很好的pid温控程序，是半导体制冷器的温控系统，还用到了labview的图形化编程(This is a very good pid temperature control process, the TEC temperature control system, also used in the labview graphical programming)

该方法适用于解决阶数比较大的线性方程组，从理论上讲这种方法是收敛的，而且具有较好的可操作性(this method is suited for some complex equation)

说明：  经典无网格教程的随书算法的例程，属于第二章例程(Classical meshless algorithm tutorial with the book routines, routines that belong to the second chapter)

一篇蛮好的文章，关于MATLAB的仿真和实例说明，包括一些simulink里面的模块说明(A fine article on the MATLAB simulation and examples, including some inside the module that simulink)

题目：有1、2、3、4个数字，能组成多少个互不相同且无重复数字的三位数？都是多少？ 1.程序分析：可填在百位、十位、个位的数字都是1、2、3、4。组成所有的排列后再去 　　　　　　掉不满足条件的排列。 (Title: There are numbers 1,2,3,4, how many can be composed of distinct three-digit numbers without repetition? Is how much? 1. Program Analysis: fill in the hundred, ten, a bit of the numbers are 1,2,3,4. Composed of all the permutations and then remove the arrangement does not meet the conditions.)

This matlab file explains the operation of Boost and buckboost converter with open loop as well as closed loop operation for voltage regulation and power factor improvement.
