Thanks Jan.
Here is the source code as attached:
function [UT1s,MagDataIAGA] = ReadIAGA1s(filename);
UT1s = zeros(1,86400);
MagDataIAGA = zeros(86400,4);
fid = fopen('ILR20071231psec.sec');
if fid > 0
disp(filename)
format = '%4d-%02d-%02d %02d:%02d:%02d.000 %3d %9.2f %9.2f %9.2f %9.2f';
[yyyy,mm,dd,hh,mn,ss,doy,H,D,Z,F] = textread(filename,format,'headerlines',13);
% for j=1:length(yyyy)
% UT1s(1,j) = datenum(yyyy(j),mm(j),dd(j),hh(j),mn(j),ss(j));
% end
UT1s = datenum(yyyy(1),mm(1),dd(1),hh(1),mn(1),ss(1)):1/86400:datenum(yyyy(end),mm(end),dd(end),hh(end),mn(end),ss(end));
MagDataIAGA(1:86400,1) = H;
MagDataIAGA(1:86400,2) = D;
MagDataIAGA(1:86400,3) = Z;
MagDataIAGA(1:86400,4) = F;
else
disp(['Can not find ' filename]);
end
The .mdg file is a MAGDAS (Magnetic Data Acquisition System) file. I saved as a .mat file
Please I do not know how to use the source code to read the .mat file. Please help me out.

a) Where did you get that code from? The fact that it requires a file ILR20071231psec.sec on the path to be present and never does anything with it (other than leaving it open) is very puzzling
b) that code is not designed to open mat files, only text files in a specific format.
