This is roughly my code Only sometimes I have less or more inputs in the array "nam" In some situations i get the error " 'subsindex' is not defined for values of class 'string'" I looked for this, but could not find it and I do not understand what the error message means.
nam = ["t1" , "t3" , "t4"];
for j=1:3
figure
title( ['title start' nam(j) ] )
end

Mattijs - is nam always an array or can it just be a string (in your code)? For example, if you have
someString = "hello";
someString(1)
What happens? Unfortunately, my version of MATLAB doesn't support creating strings (as opposed to character arrays) so I am wondering if, in some cases, your nam is just a string and not an array of strings and so treating the string object as if it were an array (using nam(j)) generates the error...

Rename the variable named title in your workspace so you can use the title function again.
When the error message refers to subsindex, it means you're trying to use an object as the index into a variable but MATLAB doesn't know how to interpret that object as an index and the variable into which you're trying to index hasn't had its indexing implemented to handle that situation.
In your case, you've done something like this but with potentially many lines between the first and second line of my example (so you forgot you created a variable named title) and with title instead of f as the name.
>> f = (1:10).^2;
>> f("5")
Function 'subsindex' is not defined for values of class 'string'.

Correct. You intend to call a function, but because you have a variable with the same name as the function and variables are higher precedence than functions MATLAB treats that code as an attempt to index into the variable.
