matlab绘图教程，教你如何绘制二维三维图(matlab drawing tutorial will teach you how to draw 2D and 3D map)

基于时隙aloha的防碰撞改进算法,效率很高哦，希望对大家有用(ALOHA anti-conclusion alogrithm dddddd)

3点法计算数值微分，你可以试试看，3dianfa jisuan shuzhiweifen (calculate the numerical differentiation using the three point method)

在这里，被控量是小车转角，向上回朔是舵机的转角，再向上就是用来控制舵机的PWM波的占空比，也就是说你的被控量是PWM波的占空比；一旦你的 舵机安装方式确定后，小车前轮的左右极限转角也就定死了，也就是说你的PWM波的占空比的变化范围也就确定了，即被控量的论域确定了，以我的为 例是1225到1725，显然S12的模糊机无法直接输出这么大的数值，在此对于输出量的隶属度函数我选用的是单值的，对应9个等级（0-8），即对应9个 PWM占空比值，即对应9个角度值。模糊语言等级、输出等级以及实际PWM占空比值的对应关系如下。 (www.hellodsp.com) 详细出处参考：http://www.hellodsp.com/bbs/viewthread.php?tid=688 )

说明：  Time Frequency Toolbox matlab时频分析工具箱,里面有各种时频分析函数，用matlab实现的，小波变换，Gabor变化，短时傅里叶变换等等(AF Ambiguity function AR Auto-regressive (filter or model) ASK Amplitude shift keyed signal BJD Born-Jordan distribution BPSK Binary phase shift keyed signal BUD Butterworth distribution CWD Choi-Williams distribution FM Frequency modulation FSK Frequency shift keyed signal GRD Generalized rectangular distribution HT Hough transform MHD Margenau-Hill distribution MHSD Margenau-Hill-Spectrogram distribution MMCE Minimum mean cross-entropy NAF Narrow-band ambiguity function PMHD Pseudo Margenau-Hill distribution PWVD Pseudo Wigner-Ville distribution QPSK Quaternary phase shift keyed signal RID Reduced interference distribution STFT Short-time Fourier transform TFR Time-frequency representation WAF Wide-band ambiguity function WVD Wigner-Ville distribution ZAM Zhao-Atlas-Marks distribution)

录制一段自己的语音信号，并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，采用窗函数法和双线性变换设计滤波器，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；最后，设计一个信号处理系统界面。(Section of their own voice recording signal, and recording the signal sampling draw sample after the speech signal time-domain waveform and frequency spectrum given filter performance indicators, using a window function method and bilinear transformation design of filters, and draw the frequency response filter then use the filter of their own design for the signal acquisition filtering, after filtering the signal to draw the time-domain waveform and spectrum, and filtering of signals before and after contrast, analysis of signal changes playback voice signal Finally, the design of a signal processing system interface.)
