How to plot x and y
显示 更早的评论
I want to plot x and y like:x=3t and y=2t with t=0->100. How can I do that ?

There are a couple of options for how you think about this problem. I might do it like this:
t = 0:100; % you could just do [0 100] because everything is linear...
plot(3*t,2*t)
But an alternative is to use the fplot function which takes in functions directly (rather than functions applied discretely to a set of points):
figure
fplot(@(t)(3*t),@(t)(2*t),[0 100])
More info can be found at the documentation pages for plot and fplot:

t=0:.1:100;
x=3*t;
y=2t;
plot(x,y);
