鄂狐贸13919971115 ______ 分别plot,绘下一段前hold on就行;或者用矩阵把函数表示出来,再对矩阵绘图.

颜仪骅4310用matlab画分段函数 如:f(x)=x*x ,在[0,1], f(x)=2*x*x - 1,在[1,2] -
鄂狐贸13919971115 ______ x=0:0.1:2; y=x.^2.*(x<=1)+(2*x.^2-1).*(x>1); plot(x,y,'-*')

颜仪骅4310matlab 绘制分段函数 x>=1,y=exp( - (x - 1)^2),x<1,y=x^2.其中曲线为绿虚线,并进行标注 -
鄂狐贸13919971115 ______ x=-4:0.1:4; y=(x<1).*(x.^2)+(x>=1).*(exp(-(x-1).^2)); plot(x,y,'--g') text(-2,5,'\leftarrow y=x^2','FontSize',9) text(2,0.7,'\leftarrow y=exp(-(x-1)^2)','FontSize',9)

颜仪骅4310用matlab如何画分段函数,y=sin(x), 当y<0时 y=0 ; 当y>0.8时 y=0.8 -
鄂狐贸13919971115 ______ x=-2:0.1:2; y=sin(x).*(x<=0.8&x>=0)+0.8*(x>0.8); plot(x,y,'*')

颜仪骅4310怎么用matlab画分段函数并把各段函数用不同颜色表示 -
鄂狐贸13919971115 ______ 把每一段分开画就行了,系统会自动画成不同的颜色的

颜仪骅4310matlab绘制分段函数图象x=30:1:350;k=0.015*x;if k>=0.1 & k=0.35 & k=1.75 & k -
鄂狐贸13919971115 ______[答案] k是数组,不能那样比较; 逻辑与是&&; j最后应该是一个数组,不是一个数; 修改如下: for x=30:1:350 if 0.015*x>=0.1 && 0.015*x=0.35 && 0.015*x=1.75 && 0.015*x

颜仪骅4310用matlab 怎么画分段函数里面包含一个指数函数? -
鄂狐贸13919971115 ______ >> syms x x=-10:0.01:3.5245; y=0.4333*x.^1.0685; plot(x,y) hold on syms X X=3.5245:0.1:10.111; Y=1.5*X-2; plot(X,Y) hold off
