Hi,
I'd like the maximum value of the x-axis to be at the point y=0.9 (graph is from 0 to 1 on the y-axis).
When I change the inputs in my function file, I want the x-axis to automatically stop when the line passes the theoretical y=0.9 line because the curve becomes asymptotic (to y=1) and makes the important bit hard to see.
Thanks.

Get the respective of x at y = 0.9..say it is xval..then use axis([0 xval 0 1]) after plotting

I can't figure out how to do that because my function y is quite complicated.

To expand, let's say the graph is a plot of y against x.
My y is:
m(:,:,3)
which is a matrix of values that come from a complicated equation involving a definite integral
and x is
v^2*t/(2*a)
