Error using fprintf Invalid file identifier. Use fopen to generate a valid file identifier. Function help
Because E is a numeric variable, it conot be used directly in your case. Use E with some formatting: fprintf('%g\n',E)

Seeking a little clarification on using sprintf with %d and formatSpec etc. to load similar *.MAT filenames that only differ in name by number.
you can use: sprintf('Band%dHz.mat', k*200);
