Try this (untested) to insert your values into columns 14 and 15 of the file:
% Open the file for reading in text mode.
inputFileID = fopen(fullInputFileName, 'rt');
% Open the output file for writing in text mode.
fullOutputFileName = 'Delete me.txt'; % Some temporary name
outputFileID = fopen(fullInputFileName, 'wt');
% Read the first line of the file.
textLine = fgetl(inputFileID);
lineCounter = 1;
while ischar(textLine)
% Print out what line we're operating on.
fprintf('%s\n', textLine);
% Read the next line.
textLine = fgetl(inputFileID);
% Insert binary values into columns 14 and 15.
outputTextLine = [textLine(1:13), binaryValue1, binaryValue2, textLine(14:end)];
% Write it out to the output file.
fprintf(outputFileID, '%s\n', textLine);
lineCounter = lineCounter + 1;
end
% All done reading all lines, so close the file.
fclose(inputFileID);
fclose(outputFileID);
% Copy new one over old one.
recycle on; % Recycle rather than delete permanently.
delete(fullInputFileName); % Delete old input file.
copyfile(fullInputFileName, fullOutputFileName); % Make new one have the same name.
delete(fullOutputFileName); % Delete temporary file.
