How to read a txt and store in a variable using the linefeed/carriage return

function readstring = read_form(textfile)
readstring = []; %empty readstring
text=fopen(textfile);
if text~=-1
while ~ feof(text)
txt= fgets(text)
h=sprintf('txt \r')
end
fclose(textfile);
end
end

This is what I did so far, but it's not working

If you want to read a text file line-by-line, do this:

% Open the file for reading in text mode.
fileID = fopen(fullFileName, 'rt');
% Read the first line of the file.
textLine = fgetl(fileID);
while ischar(textLine)
	% Print out what line we're operating on.
	fprintf('%s\n', textLine);
	% Read the next line.
	textLine = fgetl(fileID);
end
% All done reading all lines, so close the file.
fclose(fileID);
