奇异值分解（SVD）的MATLAB仿真性能分析(Singular value decomposition (SVD) of the MATLAB simulation performance analysis)

读取PhysioBank ATM数据库中的.mat心电数据，以图像显示(Read. mat ECG data from Physio Bank ATM database for image display)

对原始图像在水平方向和垂直方向与2个滤波器(低通、高通)相卷积，可以得到4块面积为原图像1/4的子图，分别为水平方向低频和垂直方向低频(HH)、水平方向低频和垂直方向高频(HG)、水平方向高频和垂直方向低频(GH)、水平方向高频和垂直方向高频(GG)。(The original image in the horizontal direction and vertical direction and two filters (low pass, high pass) with convolution, you can get the original image area of 4 1/4 graph, respectively, horizontal and vertical direction low frequency ( HH), horizontal and vertical high-frequency low-frequency (HG), horizontal and vertical high-frequency low-frequency (GH), horizontal and vertical high-frequency high-frequency (GG).)

根据实测加速度振动信号，求取功率谱密度，为疲劳分析提供数据支撑(According to the measured acceleration vibration signal, the power spectrum density is obtained, providing data support for fatigue analysis.)

QRcode标准，非常不错的学习和编码资源，有需要的朋友请下载。(QRcode standard)

该程序是实现OFDM在频带上的运用，挺好用的(The program is to achieve the use of OFDM in the band, very good use)

designing an quadrotor with pid controller

this is one of the matlab toolbox

Three matlab-based tools have been developed for the convenient assess- ment of stability conditions for linear and nonlinear systems. The fi rst is a more helpful and defi nitive version of nyquist, which has features of automatic zooming and which displays on the real axis a numeral (‘0’, ‘1’ etc.)
