运动模糊图像的复原，采用倒谱法估计模糊尺度，编写代码，适合初学者学习与理解。含图，可运行测试(Restoration of motion blurred images using fuzzy scale cepstrum estimation, writing code, suitable for beginners to learn and understand. Including maps, can run the test)

跳频仿真(frequency hopping)

PGPI(NUM,DEN,W,FI,A) plots the stability boundary locus L(KP,KI,W)in the (KP,KI)-plane for an LTI system with transfer function defined by its NUM, DEN coefficients and driven by a PI controller with transfer function, C(s)=kp+(ki/s). Frequency (W) gridding becomes important. Phase Margin, FI, and Gain Margin, A, can be defined. The method works for open loop stable or unstable, minimum or nonminimum phase systems. With Examples. Method and examples used are form "Computation of Stabilizing PI and PID Controllers" by Nusret Tan, Ibrahim Kaya and Dereck P. Atherton. MATLAB release MATLAB 7.5 (R2007b)
