说明：  基于MATLAB7的图形放大缩小移动M文件(Graphics-based Zoom MATLAB7 mobile M documents)

SSB调制模型，提倡共享。谢谢大家支持。(SSB modulation model, promoting sharing. Thank you for support. Thank you, Thank you, thank)

MUSIC算法DO模拟2个独立窄带信号入射到均匀线阵上，信号间互不相关，与噪声相互独立，噪声为理想高斯白噪声，阵列的阵元数为10，快拍数为200。阵元间距为入射信号波长的1／2，信噪比为20dB，信号入射角度差分别为5°，10°，20°。(DO MUSIC algorithm simulate two independent narrowband signals incident on the ULA, among signal unrelated, independent noise, the noise is ideal Gaussian white noise, the number of array elements of the array is 10, the number of snapshots to 200. Element spacing is 1/2 of the wavelength of the incident signal, SNR is 20dB, the signal difference between the angle of incidence was 5 °, 10 °, 20 °.)

傅里叶光学仿真，可模拟各种平顶高斯光束并对其参数进行设置。(Fourier optics simulation, can simulate a variety of flattened Gaussian beam and its parameters.)

偏最小二乘源代码，非常好用，很详细，有具体的求解过程(the process of calculate)

关于PID控制的一些例程，与薛定宇老师的反馈控制配套，与大家一起分享(PID control on a number of routines, and Xue Dingyu teacher feedback control facilities, and shared with)

可以打开图片的界面，并能完成图片的梯度计算和显示(open picture)
