应该是过零检测吧，主要是你仿真模型里有数字信号啥的，或是微积分计算啥的，如果信号可能有阶跃，那么计算结果会不一样的，但要是模型中都是连续信号，对整个系统的仿真，应该没有影响的。用于准确定位什么时候需要用更小的采样步长。MATLAB官方解释如下：可变步长求解器可动态调整时间步大小，使其在某个变量缓慢变化时增加，在该变量迅速变
rate = zerocrossrate(TT) returns the zero-crossing rate of the data stored in the MATLAB® timetable TT. If TT contains multiple channels, then the function analyzes each channel independently. example rate = zerocrossrate(___,Name,Value) specifies additional name-value arguments. Use this ...
Y -> 25x25 cell attached you will find a picture of what it looks like. I have to find the value in the red circle (see plot) and then save it for Y as well. In other words, when X reaches zero (zero crossing) the value for Y should be saved. If it is as in the pictur...

With zero-crossing detection enabled, each time a discontinuity, or zero-crossing, is detected in simulation, the solver determines the time at which the zero crossing occurred and uses this information to adjust the values of continuous states in the mo
zero crossingsparameter. You can specify whether the diagnostic is a warning or an error using theConsecutive zero-crossings violationparameter. The counter resets when the simulation progresses without detecting another zero crossing long enough for the next zero crossing to be considered nonconsecutive...
One, to detect when the input signal has a discontinuity in either the rising or falling direction Hit Crossing One or two. If there is no output port, there is only one zero crossing to detect when the input signal hit the threshold value. If there is an output port, the second zero...
To continue the simulation, you may 1) Try using Adaptive zero-crossing detection algorithm or 2) Disable the zero crossing of the blocks shown in the following table. --- Number of consecutive zero-crossings : 2002 Zero-crossing signal name : Sf0 Block type : S-Function Block path : ...

Zero crossing in audio signal signal processingI am trying to work out the zero crossing on a short audio sample of some random tom toms. I've written this script in order to capture the zero crossings:Thanks for the help. I tried replacing y(i) = []; with y(i) = NaN, but I ...
