Subscript Indices must be either real positive or logicals

I am getting above error in following code:

sets =ones(numel(fonts), numel(chars));
sets(end-349:end,:) = 2 ;

I think you need to attach or include your indices files in a .mat file to facilitate diagnosis. My guess if you look at either end, fonts, or chars one of them are not either + integers or logicals.

Only a guess without all of the info

What is the output when you run:

sets_size = size(sets)

[Walter Roberson]

numel(fonts) is probably less than 349
