How to change the values of X axis and Y axis?

I want to change the values of X axis and Y axis when I plot a Graph, i.e, put the correct numbers instead of the matrix points. thanks

Hi, I was not able to get your question clearly. Is this what you are asking ?
t = 0:0.01:2;
y= sin(t);
figure(1);
plot(y)
figure(2);
plot(t,y);
In the above code plot(y) will plot y with respect to the matrix points that is the matrix indices. The second plot that is plot(t,y) will plot it with respect to the corresponding values in t and you will see the actual numbers on the x-axis. Is that what you are asking ??

Well, this may work for you.
If you have for example:
x = [1 2 3 4 5 6 7 8 9 10]; y=[.1 3 4 .2 5 1 7 3 1 0];
And you want to be able to manipulate the x-axis as you like, you can do this:
set(gca,'XTick',[1 5 9 10] ); %This are going to be the only values affected.
Then..
set(gca,'XTickLabel',[4 8 15 21] ); %This is what it's going to appear in those places.

I'm not sure I understand what you want, so you might want to provide more specific detail. But I think you can do what you want by setting the 'XTick' and 'YTick' properties of the plot.
>> set(gca,'XTick', ... )
where you fill in a vector with the values you want in place of "...".
