How can I use greek symbols in plot labels?

Hi,

I have a plot x axis of which is formed of an array like [ 20 25 30...]

But I want x-axis to appear like lambda/20 lambda/25 etc.

Could you please help me?

Merve, you mean something like

 lambda = 20:5:40;
 y      = 1./lambda;
 plot(lambda,y)
 xlabel('{\lambda}')
 set(gca,...
    'xtick',lambda,...
    'xticklabel',{'l/20' 'l/25' 'l/30' 'l/35' 'l/40'},'fontname','symbol')
