Plot.pdf I need to plot the two piecewisely defined functions on the same graph. Please help me to write code. Thanks in advance. f(x)= 1-sqrt{5-x} for x =<5, 1 for 5=< x =<7, 1-sqrt{(x-7)/3} for x =>7. Similarly, g(x)= sqrt{(5-x)/2} for x =<5, 0...
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) =...
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?
I am trying to plot a piecewise defined function using a filter, but im getting an error 'vectors must be the same length. The graph must have 20 points. here is my code: x = linspace(-10,10,20); mask = x < 0; y(mask) = 3* x(mask).^2 + 5*x(mask) - 7; ...
通过编写一个函数,根据输入变量的不同范围计算输出值,然后使用 plot 函数绘制图像。 matlab function y = piecewise_function(x) if x < 0 y = x^2; elseif x <= 1 y = 2*x + 1; else y = sqrt(x); end end 然后在脚本中调用这个函数并绘制图像: matlab x = linspace(-2, 4, ...
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[...
