Plotting functions

How to create a variable t that takes values from 0 to 2pie with step size 0.001 . I already given de value of y. I wish to know how to plot and versus t in separate figures. What about plot and versus t in the same figure and use different colour for each graph and label each of them.

Then if I want to divide a figure in two by using the subplot command, then plot and in the upper part and in the lower part which all plots versus t. how ya??

Answer 1

[Walter Roberson]

t = 0:.001:2*pi;

For the rest, see the documentation for hold(), plot(), and subplot()

Answer 2

[Matt Fig]

To elaborate on Walter's answer:

t = 0:.001:2*pi;
figure
plot(t,sin(t));legend('sin(t)')
figure
plot(t,cos(t));legend('cos(t)')
% Now on to subplotting:
figure
subplot(2,1,1)
plot(t,sin(t));legend('sin(t)')
subplot(2,1,2)
plot(t,cos(t));legend('cos(t)')
