matlab的图形处理函数说明，是pdf文档，希望对大家有帮助(matlab graphics processing function of note is the pdf document, we want to help)

这是一个OFDM的仿真，里面的untitled.A为主函数，最后出现误码率ber的仿真图(This is an OFDM simulation, the main function inside untitled.A, last seen ber BER simulation map)

matlab的程序设计——音频信号的分析与合成、音频频谱分析仪、幅度调制(matlab program design- Audio Signal Analysis and Synthesis, audio spectrum analyzer, amplitude modulation)

Matlab中的智能控制代码，输入后修改参数再运行(Intelligent Control of Matlab code, input parameters and then run after the modification)

说明：  关于脉冲压缩的问题 。脉冲压缩的质量直接 影响雷达的探测性能。经典的脉冲压缩是通过匹 配滤波器来实现的[1 ] 。从本质上讲 ,脉冲压缩是对 发射信号的匹配滤波 ,但由于不同的目标回波信 号带有不同的多普勒信息 ,具有不确定性 ,所以它 只能是准匹配滤波(Pulse compression on the issue. Direct impact on the quality of pulse compression radar detection performance. Classical matched filter pulse compression is achieved by [1]. In essence, the pulse compression is a matched filtering the transmitted signal, but the different echo signals with different Doppler information is uncertain, it can only be quasi-matched filter)

采样时间：1E-6秒 脉冲长度：200E-6秒（脉冲宽度=200个样本） 脉冲间隔：1E-3秒（脉冲周期=1000个样本） 初始频率啁啾：DC至200 kHz（目标频率） 扫描时间：200E-6（200个样本） (Sample Time: 1e-6 sec Pulse Length: 200e-6 sec (Pulse width=200 samples) Pulse Interval: 1e-3 sec (Pulse period=1000 samples) Chirp: DC (initial freq) to 200 kHz (target freq) Sweep time: 200e-6 (200 samples))

运动目标识别，采用背景差分方法。背景图像由均值法获得。里面的视频换成前几帧换成纯背景效果能更好一点(Moving target identification, using the background difference method. Background image obtained from the mean. Which replaced the previous video frame replaced by pure background a little better results)

基于matlab的随机行走案例，希望对各位有所帮助，如有不对，还请批评指正(case based on matlab)
