please provide more of the code. There's nothing per se about xlabel('t-verdi') that should throw an error

I am guessing you have a variable somewhere called xlabel. What do you get with
which xlabel -all
it should be something like .../toolbox/matlab/graph2d/xlabel.m. If you get "xlabel is a variable", a drastically different path, or multiple paths, that is your problem.

Have you copied in pasted your code from some Windows application where ' is not the single quote that MATLAB expects?
t = 0 : 0.1 : 4;
y = 1 + exp( - 0.05 * t.^2);
plot(t, y)
axis( [ 0 4 0 3 ] )
xlabel('t-verdi')
ylabel('y-verdi' )
title('Utvikling av . . . ' )
text( 2, 2.5, 'Grafen laget 12.12.01')
gtext('Grafen er laget ved MATLAB');
If you copy your code above into the MATLAB editor, you'll see that the single quotes do not appear properly. They will appear as read apostrophes and the string is not correct for MATLAB.

copy and paste the code I've entered. I've corrected your single quotes.

What type of single quotes are you using? It could be the code formating in my browser, but your quotes look funky.
