how to use Arrays for plotting curves in for loop

Hi all,

I need some help here

I have to plot multiple curves on same graph for eg

t=0:.1:6

y1=sin(t)

y2=sin(2t)

y3=sin(3t)

.

.

.

and have to plot all this y1,y2,y3... w.r.t t on the same graph with different colors and linestyles

Since they are large in no i want to use an array for y1,y2,... and a for loop to define them and plot them all.

How can this be done????

kiran, that can be done efficiently if you store all the ys in one matrix :

 t=0:0.1:6;
 y=zeros(length(t),3);
 y(:,1)=sin(t);
 y(:,2)=sin(2*t);
 y(:,3)=sin(3*t);
 plot(t,y)

thank you.. youssef

Answer 2

t = (0:.1:6)';
y = sin(t*(1:3));

plot(t,y);

thank you, Anderi but i find it difficult to pick up y (y1,y2...) on some conditions
