plotting several quadratic functions
显示 更早的评论
would like to plot 3 to 4 qaudratic functions (a*x^2+1) on the same coordinates by changing the value of a from -1:1:2. can i use the for loop for this? many thanks

Yes, I think that it is good idea:
figure
hold all
x = linspace(0,1);
for a=-1:1:2
plot(x,a*x.^2+1)
end
hold off
legend('a=-1','a=0','a=1','a=2')
