说明：  一些基本的Matlab动画程序，可以使初学者了解动画程序的应用。(Some basic Matlab animation program that allows beginners to understand the application of animation process.)

matlab bob detection ，计算机视觉(matlab bob detection )

此代码为最佳阙值源程序:实现对图像的分割,是一种自动确定最佳阙值的方法,简单易行.(It can be applied into division of a certain picture,and behaves in a simple way with relatively better impact. )

空时编码的一个matlab实现源程序，适合初学者。(Space-time coding to achieve a matlab source code, suitable for beginners.)

1.录制一段自己的语音信号,对录制的信号进行采样 画出采样后语音信号的时域波形和频谱图 给定滤波器的性能指标,采matlab设计数字滤波器,并画出滤波器的频率响应 然后用自己设计的滤波器对采集的信号进行滤波,画出滤波后信号的时域波形和频谱,并对滤波前后的信号进行对比,分析信号的变化 回放语音信号。2.(1. Recorded his voice for some signal, the signal is sampled on the record draw sampled speech signal time-domain waveform and frequency spectrum performance for a given filter, mining matlab digital filter design, and draw the filter frequency response then use their own filters designed to filter the collected signals, to draw the filtered time domain waveform and frequency spectrum, and comparing the signal before and after filtering, analysis of signal changes playback of audio signals. 2.)
