matlab时间演示小程序 希望对大家有所帮助 大家互相学习共同进步 谢谢(a matlab program about time )

说明：  通过调用IIR5函数对所给的信号进行滤波，其中通过fdatool 设计的直接1型切比雪夫滤波器的参数保存在coefficients1.mat文件中。(by calling IIR5 function as a signal to the filter, which it adopted fdatool design a direct-Chebyshev filter parameters stored in coefficients1.mat document.)

说明：   改进的牛顿法求解： 方程的构造方法:给出[0,1]区间上的随机数(服从均匀分布)作为方程的根p*. 设你的班级数为a3,学号的后两位数分别为a2与a1,从而得到你的三次方程 例如:你的31班的12号,则你的方程是21x3+60x2+2x+a0=0的形式. 方程中的系数a0由你得到的根p*来确定. (improve Newton's method : Construction of the equation : given interval [0,1] on the random number (subject to uniform distribution) as the root equation p*. set up your classes at a3, after learning of the double-digit for a1 and a2, so you get the three equations for example : Your 31 classes on the 12th, then your equation is 21x3 60x2 2x a0 = 0 forms. the equation coefficients a0 you get from the root of p* to determine.)

大功率交-交变频调速及矢量控制技术，我从中得到很多启发，大家不妨看看(AC Power- AC variable frequency and vector control technology, I gained a lot of inspiration, we take a look)

扩展功能的DFT，可以自动扩展输入序列X，如果你输入的长度不足N，会自动以NaN补足(Extension of the DFT, can be automatically extended input sequence X, if you enter a length less than N, will automatically fill in NaN)

matlab程序优化问题及其解决方法，通过优化程序使程序运行效率更高(Matlab program optimization problems and their solutions, through the optimization program makes the program efficiency is higher)

图像进行小波分解后，对于相对来说不重要的高频成份采用较高的阈值，进行高压缩；而对集中图像大部分能量的低频成分采用较小阈值，以确保图像恢复时的质量(Image Compression)

WinQSB 数学软件，不用安装，很有用(WinQSB mathematical software, no installation, is useful)

说明：  基本蚁群算法求解TSP问题 该程序是运行过的没有问题的(Basic Ant Colony Algorithm for TSP problem is to run the program had no problem)

移动通信中基于MIMO的几种检测方式的比较，看叶看出线性和非线性在某种条件下的优劣(Mobile communications, MIMO, the comparison of several detection methods, see the leaves to be seen under certain conditions, the pros and cons of linear and nonlinear)
