code for discrete cosine transform

detect edes by canny edge detection based method

说明：  雨流计数法,建立在对封闭的应力——应变迟滞回线逐个计数的基础上,能够比较全面的反映随机载荷的全过程,由载荷——时间历程得到的应力——应变迟滞回线与造成的疲劳损伤是等效的.(Rain-flow counting method, based on the stress of the closed- strain hysteresis loop-by-count basis, can be more fully reflected random load the entire process, from the load- time history obtained stress- strain hysteresis loop and the caused by fatigue damage is equivalent.)

转速开环恒压频比控制的交流异步电机调速系统仿真(Constant speed than the open-loop control of an AC induction motor speed control system simulation)

蒙特卡洛方法的基本思想和蒙特卡洛方法的应用(The matlab codes of monte carlo method)

说明：  该程序用于分析灵敏度时调用在需要添加人工变量时将采用两阶段法求解上述问题(This program is used to analyze sensitivity when called)

很优良的PID控制器设计仿真程序与模型,经过严格检验(Very good simulation of PID controller design procedures and models, to undergo a rigorous inspection)

自己的一个实验,验证频率的采样定理.即采样点数要足够大.(own an experiment to test frequency of the sampling theorem. That sampling points should be powerful enough.)

无约束多维极值问题,适合数学计算,优化分析等极值问题的求解(Unconstrained multi-dimensional extremum problem, is suitable for mathematical calculations, the extremum problems of solving optimization analysis, etc )

本程序的目的是模拟一个ARMA模型，然后进行时频归并。考察归并前后模型的变化。(The purpose of this program is to simulate a ARMA model and then to merge time and frequency. The changes of the model before and after the merging were investigated.)
