单位阶跃信号(unit step signal)也是一个很重要的信号,定义如下: ε(t)={1t>00t<0ε[k]={1k≥00k<0 代码: t=-10:0.01:10;ya=stepfun(t,0);plot(t,ya);holdon;k=-10:10;yd=stepfun(k,0);stem(k,yd);xlabel('t / k');ylabel('f(t) / f[k]');title
Live Editor in MATLAB allows you to create an executable notebook that combines code, output, and formatted text. Learn more with videos and examples.
The MATLAB function executes during simulation at each time step. For more information about integrating MATLAB code into your Simulink models, see Implement MATLAB Functions in Simulink with MATLAB Function Blocks. If you have a Simulink Coder™ license, you can also generate C/C++ code from a...
In general, the code you generate using the toolbox is portable ANSI® C code. In order to use code generation, you need aMATLAB Coderlicense. Using Phased Array System Toolbox software requires licenses for both the DSP System Toolbox™ and the Signal Processing Toolbox™. See theGet...
The coefficients are saved in the text file that you specified, and the MATLAB Editor opens to display the file. The text file also contains comments with the MATLAB version number, the Signal Processing Toolbox™ version number, and filter information. ...

findpeaks是Signal Processing Toolbox的一项功能,用于查找加速度幅值数据的局部最大值。仅将最小高度超过一个标准偏差的峰视为台阶。该阈值应通过实验进行调整,以匹配人在行走时的运动水平,地板的硬度等。 minPeakHeight = std(accelScalarNoG);%标准差 [pks,locs] = findpeaks(accelScalarNoG,'MINPEAKHEIGHT',min...
