I want a plot to have units of \frac{e^2}{2\hbar} in stead of 1, 2, 3,...
But I can only insert the math symbols in an ordinary label and not in a yticklabel.
The plot should have an y-axis with the values 0, \frac{e^2}{2\hbar}, 2 \frac{e^2}{2\hbar}.
How do I use the yticklabel with math symbols?
figure
plot(xdata,ydata)
set(gca,'ytick',[0, 1, 2])
set(gca,'yticklabel',{'0','$$\frac{e^2}{2\hbar}$$','$$2 \frac{e^2}{2\hbar}$$','Interpreter','latex'},'FontSize',13)
title('The conductivity','Fontsize',15),
xlabel('Photon energy [eV]','Fontsize',13)

The following style is work for labeling. Please use it for your purpose.
ylabel('$\displaystyle\frac{e^2}{2\hbar}$','interpreter','latex')

you can't use latex in yticklabel (unfortunately). you're gonna have to use text if you really want to insert math symbols.
something like :
clear all
figure
xdata = 0:0.01:10;
ydata = sin(2*xdata)+1;
plot(xdata,ydata)
set(gca,'ytick',[0, 1, 2],'yticklabel',[])
tt(1) = text(-0.5,0,'0');
tt(2) = text(-0.5,1,'$$\frac{e^2}{2\hbar}$$');
tt(3) = text(-0.5,2,'$$2 \frac{e^2}{2\hbar}$$');
set(tt,'Interpreter','latex');

There is a way but you need to use the 'TickLabelInterpreter' property. Here is an example:
figure()
a = axes;
plot(xdata,ydata);
set(gca,'YTick',[0, 1, 2]);
set(a,'TickLabelInterpreter','latex');
set(gca,'YTickLabel',{'0','$$\frac{\textrm{e^2}}{\textrm{2\hbar}}$$','$$2 \frac{\textrme^3}}{\textrm{2\hbar}}$$'});
ylabel('\bf{Y values}','fontsize',14);
xlabel('\bf{X}','fontsize',14);
