Adding Greek Characters To Plots

[Thomas Markovich]

Hi,

So I have a few different parts of the various plots that I am trying  
label with greek characters. The first is, I would like my tick marks  
to be at every pi/2 but obviously, I would like the pi symbol. I have  
found the command set(gca,'xtick',-2*pi:pi/2:2*pi) and  
set(gca,'XTickLabel',{'-pi','-pi/2','0','pi/2','pi'})
, however this only gives the numbers and no symbols.

Also, I would like to set an axis label for Y that is f(phi) and for  
X, phi. Additionally, I would like to label my graphs with V(phi) for  
one and \Psi_{1+} for the other. I have found the command
xlabel()
ylabel() But I can't figure out this one either.
