确保在实际应用中正确设置和连接信号,以避免出现’Error: ** during flag= call must be a real vector of length 3’的错误。 通过遵循上述解决方案,你应该能够成功地在MATLAB Simulink中使用BP PID控制器,并避免遇到’Error: ** during flag= call must be a real vector of length 3’的错误。如果问题仍...
a maximum of N successive negative values in F are to be converted to 0 with all the possible remaining negative values, if any, unaffected? If so, the example you should have used ought to have demonstrated that behavior. In any case, here is code that ...
MATLAB还允许创建n个对数值间隔相同的行向量。使用格式为: logspace(a,b,n) >>logspace(1,2,5) ans= 10.0000 17.7828 31.6228 56.2341 100.0000 另一个例子 >>logspace(-1,1,6) ans= 0.1000 0.2512 0.6310 1.5849 3.9811 10.0000 1. 2. 3. 4. 5. 6. 7. 特征化向量 ①命令length返回向量中包含元素的...
I don't know how many times I needed to rewrite this function. Its such a simple thing, hardly worth sharing, but now I won't have to rewrite it anymore. I needed to iterate over a length-N vector from a start vector to a finish vector and at each iteration, check some conditions....
MATLAB Online에서 열기 I would like to index an N-dimensional array with a vector of length N. In particular, for the 2-dimensional case I am currently doing the following. A = rand(10); v = randi(10,1,2); v = num2cell(v); ...

Problem is that my x-axis for these variables don't match. Left figure have x-axis 0-8793 while the right figure have 8972-17495. They are equal in length and they represent the same actual time span but the internal x-vectors don't match. The comparison plot on the left is supposed...
Open in MATLAB Online Hello Everyone! I am required to add a vector 'rpm' as a slider in the quiver plot. I am plotting the vector fields of reaction forces(x and y components). I want the vector fields to change as I change the Slider('rpm'). I am including my code with t...
centers = diff(edges(1:2))*[0:(length(n)-1)] +mean(edges(1:2));figure('color','white'); bar(centers, n); xlabel('Angle (degrees)') ylabel('Frequency') title(sprintf('Histogram of angles between coneDir and random points: %d deg', coneAngleDegree)) ...
