Should this be backported to 4.5?

Yes, please

Commit 30361ccb cannot be automatically cherry-picked. I think this has to do with the fact that M_.param_names is a cell-array in unstable, while it is a character-array in 4.5. Can you possibly tell me how this should be adapted (or submit a merge request on 4.5)?

In 4.5, the line needs to be

    param_names_tex='';
    for ii=1:size(options_mcf.param_names,1)
        param_names_tex=strvcat(param_names_tex,strrep(options_mcf.param_names(ii,:),'_', '\_'));
    end

Thanks. Actually I just pushed another solution (converting to and from a cell array). Please check that it is ok.

Your solution is a lot more elegant and should therefore be ported to model_comparison.m in master
