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: mne_load_coil_def.m
    path of file: ./repos/malini/Codes/deconvolution - model/spm8/external/mne
    
    the code of the file until where you have to start completion: function [CoilDef,Header] = mne_load_coil_def(fname);
%
%
%   [CoilDef,Header] = mne_load_coil_def(fname);
%   CoilDef          = mne_load_coil_def(fname);
%
%   If file name is not specified, the standard coil definition file
%   $MNE_ROOT/setup/mne/coil_def.dat or $MNE_ROOT/share/mne/coil_def.dat is read
%
%   The content of the coil definition file is described in
%   section 5.6 of the MNE manual
%
%   This routine is modified from the original BrainStorm routine
