I want the greek letter on my legend to look like as it does in LaTeX. Here is the code:
clc;
clear all;
phi=[1/2,1/3,1/4];
l=-0.1:.05:.1;
p = @(x,phi,l) 1/3.*(exp(x.^(phi))-1)./(exp(x.^(phi))+1) + l;
x=linspace(0,.2,101);
for k2 = 1:length(l)
figure(k2)
legendCounter = 1;
for k1 = 1:length(phi)
pValues = p(x,phi(k1),l(k2));
if any(pValues >= 0)
plot(x, pValues)
drawnow;
hold all
ar{legendCounter} = sprintf('{\\it\\phi_{state} =}%s',rats(phi(k1),3));
legendCounter = legendCounter + 1;
end
end
grid
axis([0 .21 0 .25])
hold off
legend(ar, 'Location','best')
plot2svg(['a=',num2str(k2),'.svg'])
end
Even though the greek letter looks fine on the matlab screen, when I see the resulting .svg file, it looks different. Is there any way to adjust this?

You could try setting the interpreter to LaTeX:
legend(ar, 'Location','best','Interpreter','latex')
For this to work, you'll have to reformat the equation so there are dollar signs around it:
ar{legendCounter} = sprintf('$\\phi_\\mathrm{state} =%s$',rats(phi(k1),3));
While I was at it, I made the subscript into Roman characters because that is better style when the subscript is not a variable.

The problem is in the .svg file. Somehow the .svg shows something different, even after setting the LaTeX interpreter like you did (see attached file).

If you're using plot2svg from the File Exchange, your best bet is probably to ask its creator.
