基于matlab的低通有源滤波器设计wp=30hz，ws=40hz，rp=0.5，rs=40，fs=100hz. (Matlab-based low-pass active filter design wp = 30hz, ws = 40hz, rp = 0.5, rs = 40, fs = 100hz.)

此程序为统计风电出力差的概率密度，已有excel文件可以替换为自己数据。概率和为1(This procedure for wind power output difference of statistical probability density, existing excel file can be replaced with your own data. Probability is 1)

说明：  matlab中的关于代数方程组的解法实验方面的例子和程序(matlab in the solution of algebraic equations in terms of examples and experimental procedures)

说明：  这是一个用matlab读取txt（特定格式）文件并读取文件，画出figure，自动保存和关闭figure。程序运用了深度搜索递归算法。（因为大家没有input的txt文件，所以阅读程序领会思想和方法即可）(This is a use matlab to read txt (a specific format) file and read documents, painted figure, on and off automatically to preserve figure. Procedures for the use of recursive depth search algorithm. (Because there are no input of the txt file, so reader can understand the ideas and methods))

说明：  数字信号处理课程设计程序，实现频分复用，低通带通高通滤波器进行滤波。(Digital Signal Processing design process, to achieve frequency division multiplexing, low-pass band-pass filter high-pass filter.)

详细阐述了vc和MATLAB混合编程的实现方式，方法，学会如何在matlab中用c语言进行编程开发(Elaborated vc mixed programming and MATLAB implementations, methods, learn how to matlab programming using c language development)

matlab simulink 实现对控制对象的预测控制(matlab simulink realization of the control object predictive control)

Fisher program 图片处理程序，报告搜索Fisher (Fisher program image processing procedures, reports Search Fisher)

用matlab打开视频，并测试处理30帧图像需要的时间(Using matlab to open the video, and test the processing time of 30 images)

本代码是基于matlab开发的用于图像处理中针对灰度图像进行的直线匹配检测(Detect lines in grayscale image by matlab)
