Help, How can I write the symbol " theta" in Matlab

Hi friends, I have a problem with a graphical presentation of my results in Matlab. I will write a symbol theta  on the Y axis ( Dimensionless temperature ) but when I put it in my code it will show me "?" I don't know why...! Besides, I searched on the internet, ho, someone tells me that I have to use the code "Asci" but I don't know how doing it. ??? help me please

program figure(7); plot(x,TF,'-r','linewidth',1.5) hold on plot(x,TS,'-k','linewidth',1.5) xlabel('length ','FontSize',12) ylabel('Dimensionless temperature ','FontSize',12) legend('Thetaf','Thetas',1)

   aH = axes;
   plot(rand(10,1));
