Hello everyone
I have the following arrays of relevance to the question:
substrates=["MgO" "SiO2" "W"];
substrates_title=["MgO" "SiO$_2$" "W"];
which I want to be introduced in the title of a plot and in the name of the file that encapsulates the aforementioned plot in a for loop. For that, I have written preliminarily the following lines related to this:
t1=title(['Thermal background $T=\,$',num2str(Temperature(i)),' K, ',substrates_title(l),''],'FontSize',14,'interpreter','latex')
...
saveas(gcf,fullfile(outputdir,['Scaling_Based_Temperature_Dependent_Phase_Diagram_Thermal_Background_T=',num2str(Temperature(i)),'_K_with_Joule_Heating_',substrates(l),'_Substrate.pdf']))
but this does not work, exceptly the num2str(Temperature(i)) that works perfectly.
Any suggestion?

Part of the problem is that you are mixing character arrays and strings. The following works (after you set your own outputdir):
i = 1;
l = 1;
Temperature(i) = 273.15;
outputdir = 'SET ME TO WHAT YOU WANT!!';
substrates={'MgO' 'SiO2' 'W'};
substrates_title={'MgO' 'SiO$_2$' 'W'};
t1=title(['Thermal background $T=\,$',num2str(Temperature(i)),' K, ',substrates_title{l},''],'FontSize',14,'interpreter','latex')
fname = ['Scaling_Based_Temperature_Dependent_Phase_Diagram_Thermal_Background_T=',num2str(Temperature(i)),'_K_with_Joule_Heating_',substrates{l},'_Substrate.pdf'];
saveas(gcf,fullfile(outputdir,fname));
Note that I used a cell array of character arrays, rather than strings. One could probably have done the opposite.
