PCA MATLAB CODE AND SLIDES

1.将rddata程序运行后，会出现.mat文件，选择不同数据， 更改.m文件中.mat的文件名，如ecgdata100.mat。 接着运行ecgdata.m文件，对load命令中的文件名进行选择修改， 可以实现对QRS波的检测。 2.将MIT-BIH库中的数据100.dat,101.dat,102.dat,106.dat,108.dat,117.dat,118.dat, 123.dat运行rddata程序，生成相应的.mat文件，接着，运行gui.m文件，会 出现心电信号选择界面。(1 to rddata run, it will appear. Mat files, select a different data, change. M file. Mat file name, such as ecgdata100.mat. Then run ecgdata.m file for load command to select the file name changes, you can achieve the QRS wave detection. (2) the MIT-BIH database data 100.dat, 101.dat, 102.dat, 106.dat, 108.dat, 117.dat, 118.dat, 123.dat run rddata program to generate the corresponding. Mat file, then run gui.m file selection screen will appear ECG.)

带有裂缝的动力分析模型，采用abaqus软件建模(Dynamic analysis model with cracks, software modeling using abaqus)

与理论分析结果相比，采用了小波去噪的思想，一种流形学习算法（很好用），旋转机械二维全息谱计算，结合PCA的尺度不变特征变换(SIFT)算法，是一种双隐层反向传播神经网络。

This exercise uses a Matlab file DigiTrans.m" for simulation of a digital transmission scheme using 16-QAM data. . We will use these Matlab functions during the second assignment. To familiarise yourself with both the Matlab file, the practical idea of a digital transmission scheme and its issues, some parameters in DigiTrans.m" need to be adjusted. 模拟整个通信数字传输系统, 并有生成眼图和误码率,很有参考价值.

matlab与c#结合开发图形界面,在c#的picturebox中调用matlab的figure图像界面(matlab develop program)

仿真电磁波在空间中的传播过程，并制作演示动画。(Simulate the transportation progress of an EM wave in space, and make a movie showing the progress.)

谱聚类，一种更强大、 更专业的算法 （与 K-均值相比），它的名字源于图的谱分析......

串的一些基本运算，删除一段子串，置换，求s串中从start位置开始长度为len的子串等等(Some of the basic string operations, delete a substring, replacement, seeking s string starting from the start position of the sub-string of length len, etc.)

极好的有限元结构动力学分析算例，为初学者带来福音(good example for dynamic analysis)
