Warning: Unable to interpret TeX string

The error shows up when using this:

   306 saveas(gcf,save_jpg);

Warning: Unable to interpret TeX string "M:\Data\D201412"

It works fine to save files into sub-folder "folder1/folder2/..." etc, But to access up folders "\" has to be used, such as:

   path(path,'C:\Users\user1\Documents\Matlab\library')
   foldername = "M:\Data\D201412";

This appears.

The backslant (\) character is a control character in TeX. If you want to have it display correctly, you need to use the double-backslant (\\) to display a single backslant correctly.

Esample:

figure(1)
scatter(rand(50,1), rand(50,1), '+')
title('M:\\Data\\D201412','Interpreter','tex')

The double-quote (") could be a problem as well. If you want to include those, you have to enclose them as part of the string, in single quotes:

'"M:\Data\D201412"'
