matlab对机械四杆结构的仿真动画，很难找的，很有价值。(matlab mechanical simulation of four-bar structure animations, it is difficult to find, great value.)

没什么好东西！只是BP，PID算法而已！可以看看过得去(nothing good things! Only BP, PID algorithm! Can look at the little things)

gsm location finder for the gsm modem accurately by AT commands..

this file is a graphical user interface (GUI) using Matlab and simulink it is for DC Drive. it is a PI cascade controller ( current and speed controller). it a good and friendly GUI
