How to convert to latex display from a cell array?

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

This is what I have tried, but Matlab doesn't seem to like it...

Any comments and help is highly appreciated, and thanks for your time and effort in advance!

Best,

Ben

Hi Ben,

please try this

set(h,'LineWidth',4); title(['\',index{count}]) ,'FontSize',20);

instead of

set(h,'LineWidth',4); title({\index{count}},'FontSize',20);

Best regards,

Friedrich
