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) =...
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; ...
Try define another function. Then "hold on"; and plot the function. Amna Habib2021년 9월 12일 Ok, Thanks a lot! 댓글을 달려면 로그인하십시오. 추가 답변 (0개) 태그 plot piecewise fun...
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[...
function F=Piecewise_x(x) F=x.^2.*(x>=0 & x<1)+cos(pi*(x-1)).*(x>=1 & x<2)+(-x.^2./(x+2)).*(x>=2 & x<=4); end 运行: x=linspace(0,4); F=Piecewise_x(x);%计算相应函数值 plot(x,F);%绘制曲线 hold on; ...
1.一元分段函数绘图例如：把下面的函数保存为Piecewise_x.m文件function F=Piecewise_x(x)F=x.^2.*(x>=0 & x<1)+cos(pi*(x-1)).*(x>=1 & x<2)+(-x.^2./(x+2)).*(x>=2 & x<=4);end运行：x=linspace(0,4);F=Piecewise_x(x);%计算相应函数值plot(x,F);%绘制曲线...

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...
