低通Chebyshev 1型滤波器，通带边界频率为1500Hz，通带波纹小于3dB，阻带边界频率2000Hz，阻带衰减为40dB，采样频率为8000Hz(Low-pass Chebyshev 1 filter passband edge frequency of 1500Hz, less than 3dB passband ripple, stopband edge frequency 2000Hz, stop-band attenuation of 40 dB, the sampling frequency to 8000Hz)

Matlab图像处理基本操作及摄像机标定(Calibration of Matlab camera and image processing basic operation)

image and signal processing are used mostly right now. these programs is related to image processing. Image negative is used for the getting the negative image of the original image. and contrast stretching is for the give the middle value. Fast Fourier Transform program is used for the getting FFT of the signal.

该GUI可用于调节任何可控的非线性系统到用户指定的设定点。它使用切换李亚普诺夫控制函数。非线性系统可以是任何阶的，并且不限输入的数目。(This GUI can be used to regulate any controllable nonlinear system to a user-specified setpoint. It uses a switched Lyapunov control function. The nonlinear system can be of any order and with any number of inputs. )
