PLOT TWO FUNCTION IN THE SAME GRAPHIC

Hi everybody,

Another way to view two functions in the same graphic without using the command 'plot'?

Thanks a lot,

Mariana

Yes. "hold on" works for most graphic routines. (There are some graphic routines which are defined to open their own figure.)

Thank you Walter,

The problem is that my first graph is generated by a little program in matlab, and i wanna add a function to that graph. I try with HOLD ON.

Walter,

I get it, but now i want to label a point.. my codes are:

>> hold on;
>> x1=-5:5;
>> x2=-2/3+2/3*x1;
>> plot(x1,x2,'Color',[.7 0 0]);
>> hold off;

If i want to label the point (4,4) what codes to write?.. Thanks for your help!
