根据上述思路,我们可以编写以下MATLAB代码来实现分段函数并绘制函数图像:[function plot_piecewise_function(h, D) x = linspace(-2*D, 2*D, 1000); % 生成一组x值,范围为[-2D, 2D] y = zeros(size(x)); % 初始化y值为0 % 计算函数在不同区间的取值 y(x > D) = h; y(abs(x) <= D) =...
Piecewise[{{20,Abs[x]<=5&&0<=y<=10},{25-Abs[x],5<=Abs[x]<=20&&0<=y<=10},{30-y,Abs[x]<=5&&10<=y<=25},{20-Sqrt[(Abs[x] - 5)^2 + (y - 10)^2],Sqrt[(Abs[x] -5)^2 +(y -10)^2]<= 15}}, 5] 公式可视化结果: 绘图结果为: Plot3D[Piecewise[{{20,Abs[...

Open in MATLAB Online Ran in: When I try to run your Code directly, without any changes. I do not see any error, rather I get a piecewise plot with 20 points. x = linspace(-10,10,20); mask = x < 0; y(mask) = 3* x(mask).^2 + 5*x(mask) - 7; ...

I'm trying to plot the above periodic function on the interval -10 < t < 10 I can plot it once using: pw = evalin(symengine,'piecewise([t > -2 and t <= 0, -t^2],[t >=0 and t < 2, t^2])'); fplot(pw) How would I plot this function on the interval?

Matlab中的piecewise函数可以方便地表示分段函数。例如,对于以下分段函数: f(x) = {x+1 , x<0 {x^2 , x≥0 可以用以下代码表示: syms x f = piecewise(x<0, x+1, x>=0, x^2) 三、分段函数的绘制方法 在Matlab中,可以利用plot函数绘制分段函数的图像。以下是绘制分段函数的步骤: 1.定义分段函数...
