calcula a viga usando uma formula de mecanica dos solidos simples

里面收集了matlab的绝大多数命令，是matlab初学者的一个很好的工具！

c程序，子函数chirp（）产生周期性chirp信号，即线性调频信号。(c procedures, Functions chirp () have a periodic chirp signal, that is, the linear FM signal.)

啁啾脉冲对传输特性的影响，用MATLAB实现可视化(chirp pulse)

基于Wiener滤波的语音消噪Matlab源程序 调用方式： output=WienerScalart96(signal,fs,IS) signal－－输入含噪语音 fs－－－－语音信号采样率 IS－－－－起始静音端，用来估计噪声方差（秒做单位，默认是0.25秒） (Wiener filter-based de-noising of the voice call Matlab source code the way: output = WienerScalart96 (signal, fs, IS) signal- voice input with noise fs---- voice signal sampling rate IS---- Start mute end used to estimate the noise variance (units of seconds to do, the default is 0.25 seconds))

基于SIFT的光流运动检测，能够解决遮挡问题，有效提高检测的精度。(SIFT-based optical flow motion detection, can solve the occlusion problem, improve detection accuracy.)
