主成分分析的Matlab程序，包括完整的计算过程，相关参数计算及绘图(Principal component analysis)

小波神经网络的源程序，稍加扩展可用于多样本数的的训练(Wavelet neural network of the source, this little extension can be used for various numbers of training)

ofdm和qam完整仿真程序，并且比较两者，希望大家(ofdm qam and integrity simulation program, and comparing the two, we hope to s)

MATLAB图像处理源文件，每章节的对应matlab源代码已整理好，可对应ppt和视频配套学习(MATLAB image processing source files, each chapter corresponds matlab source code has been collated.)

要求使用继电自整定方法对其实施自适应PID控制。 1、选择采样时间0.1s，把对象离散化。 2、加继电（开关）控制，测量对象的Tc,Kc。 3、利用ZIEGLER-NICHOLS 公式表，确定PID参数。 4、实现闭环控制。 5、根据调节效果，修正PID参数。 (Require the use of relay tuning methods for its implementation of the adaptive PID control. 1, select the sampling time 0.1s, the discrete objects. 2, plus relay (switch) control, measurement object Tc, Kc. 3, using ZIEGLER-NICHOLS formula table, determine the PID parameters. 4, closed loop. 5, according to moderating effect, the amendment PID parameters.)

本程序是用MATLAB编写的用于仿真通信系统中信号经过QPSK和16QAM调制后，通过高斯白噪声和瑞利衰落信道的星座图仿真(This program written by MATLAB is for the students who are studying telecommunication.It s very useful to simulate the signal constellation.)

neural network is established

自适应卡尔曼滤波的详细论述，附有卡尔曼滤波的程序实现，(Adaptive Kalman filter in detail, the procedures for implementation with Kalman filtering,)

nearestSPD works on any matrix, and it is reasonably fast. As a test, randn generates a matrix that is not symmetric nor is it at all positive definite in general.
