对白噪声的谱熵进行了计算。大家可以参考一下，(Spectrum Entropy )

2D FFT in matlab. inputs are original data and block size. ex) block size = [8 8]

图像模板匹配算法用MATLAB来试验，有例子大家可以看看，有上占还不完好，有能力的自己改改(Image template matching algorithm using MATLAB to test, there are examples we can see, there are not well accounted for, the ability of their changed)

matlab scripts for some image processing applications like windowing,zooming etc

系统可以利用声音信号产生带有回声的声音文件，并可以从带有回声的文件中消除回声而得到原声音信号；另外，系统还能从中估计反射物的距离(System can make use of the voice signals of the sound files with echoes and echoes from the document with echo and obtain the elimination of the original voice signal In addition, the system can also have to guess the distance from the reflective material)

buck 非线性 仿真模拟中 的逻辑电路模型 源程序(buck nonlinear simulation logic circuit model source)

说明：  用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图(fft analysis,plot rms spectrum,power density spectrum, etc.)

说明：  一个小小作业~解双曲线微分方程 大家要下就下吧呵呵~(~ Solutions for a small job, under the hyperbolic differential equation we have to lower it Ha ha ~)

说明：  潮流计算，使用PQ分解法，是一种比牛顿法更优越的潮流计算法，收敛速度更快，收敛精度与牛顿法相同(power flow of P-Q)

说明：  folyd用来处理图论中最短路径问题。对传统的folyd算法进行了优化。(folyd to deal with the shortest path in graph theory problem. Folyd the traditional optimization algorithm.)
