I am trying to use this code to name the title of my figure (this is done in a loop). (strings stored in cell array are called ) However, when i do so, the numbers are always positioned in a wierd manner, almost like a subscript to the text.

files = dir('*.mat'); 
for ie=1:length(files)
load(files(ie).name)
[path name exten]=fileparts(files(ie).name); 
theconvert{ie}=cellstr(name);
figure;
    plot(1:size(MSD_averaged,1),MSD_averaged,'o','Markersize',10, 'color',rand(1,3));
    ylabel('Instantaneous MSD', 'FontSize',100);
    xlabel('Track number', 'FontSize',100);
    title(theconvert{ie}, 'FontSize', 30);

However, after using the code if a the string was called 'channel_1'. The title would come in such a manner that, 'channel' would look fine but '1' would look like a subscript. Any help is welcome. Thank you.

In certain instances, MATLAB interprets an underscore (_) as a subscript. The easiest way to force it to treat the underscore as just that is to put a backslant (\) ahead of it: \_. Setting 'Interpreter','none' also works, but it also disables other TeX or LaTeX code from rendering.

Thank you Star Strider. That was quite helpful. If I may, I am having another issue using the strings from cell array with 'print'. It doesn't seem to be taking the strings from the same cell array that I am using for the figure title. Is there any reason why this would be happening?

My pleasure.

Note that the print function prints or saves a figure object. The sprintf (and fprintf) functions print strings.

You have to address cells with curly braces {} to print the contents of specific cell elements. (The print functions don’t accept cell arguments because cells can contain anything.)

For example:

strc = {'This is a string in a cell.'};
Q1 = sprintf('%s', strc{1})                 % Uses ‘{}’
Q2 = sprintf('%s', strc)                    % Without ‘{}’
Q1 =
This is a string in a cell.
Error using sprintf
Function is not defined for 'cell' inputs.
Error in WHITEBOARD (line 698)
Q2 = sprintf('%s', strc)
