说明：  一个有关OMP的应用的例子，适合初学者学习 正交匹配追踪方法(An example of application of relevant OMP, suitable for beginners The principal component analysis method)

无刷直流电机 伺服控制系统仿真 精华,对转向器等方面有用(The brushless DC motor servo control system simulation the essence of the steering gear and other useful)

Matlab 二维离散余弦变换的图像压缩(Matlab dimensional discrete cosine transform image compression)

用MATLAB实现ASK,FSK,PSK的程序(ASK, FSK, PSK program in MATLAB)

分析了正弦信号分辨率问题，当采样频率相同时，点数越多，分辨率越高，频谱特性误差越小( Analysis the problem of resolution in a sinusoidal signal.When the sampling frequency is the same, the more points,the higher the resolution,and the error spectral characteristic is smaller.)
