VCO_best_feedback

algorithm to find stock price wave when using positive return rate as wave condition.For example, find the S&P500 index whole waves, whose change rate is more than 5 from bottom to top.

fish 快速图象分割 内含4个Matlab应用程序

可以仿真出2PSK的误码性能，并以此为基础可以仿真出MPSK的误码性能(2PSK can simulate the error performance, and on this basis can be simulated BER performance of MPSK)

Matlab的常用函数，查阅十分方便，不用再翻阅书籍那么麻烦(Matlab commonly used functions, access is very convenient, no longer need to read books so much trouble)

principal component analysis+ databases

可以提取出图像中的红色信息，坐标空间变换（直角坐标系到极坐标系），彩色模型变换（RGB到HSI）(Red information can be extracted in the image coordinate space transform (Cartesian coordinates to polar coordinates), color model transformation (RGB to HSI))

巴特沃斯滤波器设置，自行设置阶数、截止频率等滤波器参数(butter-worth filter)

This is description of simulink and matlab software

说明：  采用db1基本小波来分解信号,比较第三层近似信号与原始信号,重构最大误差,比较第三层近似信号与原始信号.(used db1 to the basic wavelet decomposition signal, the third layer approximate comparison with the original signal signal, the largest reconstruction error Comparing the third layer similar to the original signal with the signal.)

一个很好的运用模拟退火解决0-1背包问题的一个例子程序(A good use of simulated annealing to solve 0-1 knapsack problem an example program)
