how to plot points in a loop?
显示 更早的评论
for x=1:10
a=2*x
b=3*x^2
plot(a,b)
end
But the figure cannot be plotted. What should i write for the codes?

@Chen Ji: do you want the points to be joined by a line?

figure()
hold on
for ...
...
plot(a,b,'*')
end
But I would not recommend doing this: the simpler MATLAB solution would be to write vectorized code:
X = 1:10;
A = 2*X;
B = 3*X.^2;
plot(A,B,'-*')
