You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: fiff_write_ctf_comp.m
    path of file: ./repos/spm12/external/mne
    
    the code of the file until where you have to start completion: function fiff_write_ctf_comp(fid,comps)
%
% fiff_write_ctf_comp(fid,comps)
%
% Writes the CTF compensation data into a fif file
%
%     fid           An open fif file descriptor
%     comps         The compensation data to write
