Design an x-y plot for the following where the values of x are from 0 to 20π with a spacing of π/100.

a. y = x.sin(x)

b. z = x.cos(x)

c. Convert the above 2D into a 3D plot using z as the third axis

在 MATLAB Online 中打开

try this..

x=0:pi/100:20*pi;
y=x.*sin(x);
z=x.*cos(x);
plot(x,y);
plot(x,z);
plot3(x,y,z);
grid on;
