Find the minimum of a function on a plot and where it occurs on the x-axis

So I'm new to MatLab and I have a function that's plotting temperature vs time in hours and I need to find the minimum temperature and which hour it occurs on the x-axis. Is there any way to find this using a function and only use one line of Matlab? Thank you

I would recommend fitting your data to a function (use fit() function), then finding the minium temperature would be easy. Why do you care about how many lines of code? If you just want the minimum of your discrete data then:
[Min,idx]=min(temp);
Time=t(idx);

You have a function of one variable. Perhaps you should spend some time reading about tools like fminbnd, or even fminsearch. Either of those tools would solve your probem.
In the docs for those functions, you will see examples of how they can be used.
