semilogy(x,exp(x));
hold on;
semilogy(x,2*exp(x));

Thank you. Please, how we can change the Y axis. Y [0, 0,08]

[TADA]

Sorry, I don't understand, what do you want to put in your Y axis?

what is that Y vector you wrote?

Answer 3

[Yuriy Gamiy]

Sorry, Can we call axis Y [0, 0,08] or Axis Y diapazon [0, 0,08] ?

[TADA]

If what you want is to change the label,

you can use

ylabel('something something');

and name it whatever you want
