What is the difference between this question and your earlier http://uk.mathworks.com/matlabcentral/answers/246658-how-to-convert-output-to-integer ?

fprintf(fid, '%x\n', b);
where the format specifier '%x' exactly means hexademical. If you want another number format, then you need to read the fprintf documentation and pick a format specifier that suits your needs: there are many options, so it is worth reading the documentation carefully. You might like to start with %d:
fprintf(fid, '%d\n', b);
