You are getting confused between the command syntax and the function syntax. In particular you are trying to use the command syntax with a variable named files, which will never work as the line of code

load files

is interpreted as

load('files')

Where 'files' is treated as a string, not a variable. This is specifically explained in the load documentation: Do not use command form when any of the inputs, such as filename, are variables. The easiest solution is do not use the command syntax in your code, only use the function syntax and then you will never face this problem again. Try this instead:

filenames = {'data1.mat','data2.mat','data3.mat'};  
for kk = 1:numel(filenames)
    S = load(filenames{kk}) % Best to load into an output variable.
    ..
end

Also note that I fixed the cell array indexing to use the correct {} braces , removed the char operation which is completely unnecessary as the contents of the cell array filenames are already of class character, and for robustness loaded the file data into an output variable (which is a scalar structure).
