MATLAB: How to save a text file with headers

Question

For context, the full code reads data from a text file, calibrates and converts the data to degrees, and then saves the new data in 4 columns with 108766 rows each. This is what I am currently using to save the new text file:

function calibratedData = applyCal(fname,Ey,components,rawData,Calib)
% applies calibration (gain and shift) to raw data; function returns
% calibrated data ONLY for 'components'!
calibratedData = [];
for i = find(components)
    calibratedData(:,Ey(i).datacolumn) = ( rawData(:,Ey(i).datacolumn) - Calib(1,Ey(i).datacolumn) ) * Calib(2,Ey(i).datacolumn);
end
%save as textfile:
s = strtok(fname,'.');
SaveName = [s, datestr(now, ' yyyymmddTHHMMSS'),' calibrated.txt'];
save (SaveName, 'calibratedData', '-ASCII');
end

This works – but I need there to be a header at the top of each column. The headers need to be "LE Horizontal" "LE Vertical" "RE Horizontal" and "RE Vertical". Any help would be appreciated! Thank you!

function calibratedData = applyCal(fname,Ey,components,rawData,Calib)
% applies calibration (gain and shift) to raw data; function returns
% calibrated data ONLY for 'components'!
calibratedData = [];
for i = find(components)
    calibratedData(:,Ey(i).datacolumn) = ( rawData(:,Ey(i).datacolumn) - Calib(1,Ey(i).datacolumn) ) * Calib(2,Ey(i).datacolumn);
end
%save as textfile:
s = strtok(fname,'.');
SaveName = [s, datestr(now, ' yyyymmddTHHMMSS'),' calibrated.txt'];
names={'"LE Horizontal"','"LE Vertical"','"RE Horizontal"','"RE Vertical"'};
writecell(names,SaveName,'delimiter','space');
save(SaveName, 'calibratedData', '-ASCII' '-append');
end

saves having to create the table just for the purpose of writing a header line. Second time come up in last couple of days...see
