Dear all:

I am having trouble to display Greek in latex form. I have a cell array contains the following:

    index = [ {'alpha'};
              {'sigmaL'};
              {'beta'};
              {'theta'};
              {'rho_a'};
              {'kappa_y'};
              {'kappa_pi'};
              {'var_eps_a'};
              {'var_eps_r'}];

Each of the cell in cell array 'index' represents a variable name and I want to plot each in one figure by using subplot. In each of the subplot, I want to have a title as the name of the variable in latex form. I know I can manually do so by adding a slash to the string, for example:

title('\fontsize{20}\alpha')

But I want to assign the name directly by referring to the cell array 'index' rather than typing the name explicitly, since in some cases not all variables are needed and I want to build a automate way to plot the variable.

count = 1;
for i = 1:row
    for j = 1:col
        subplot(row,col,count);
        h = plot(bar_x(count,:),bar_y(count,:),'r',...
            likelihood_region_Xaxis(count,:),likelihood_region(count,:),'b');
        set(h,'LineWidth',4); title({\index{count}},'FontSize',20);
        count = count + 1;
    end
end
