Given an input .txt file, how can I extract the first letter of each line of that file.
Ex: file.txt is
I’ve worn a black suit
my entire life. It suits the war
my eyes ignite.
My sins sit on my lap,
bald, blind, desperate
for the mercy of lost roads,
glottal white lines.
Would output: 'Immmbfg'

Did you see the help for fgetl()? Just modify it to add an array for the first characters of the lines:
fid = fopen('fgetl.m');
tline = fgetl(fid);
lineNumber = 1;
while ischar(tline)
disp(tline)
firstCharacters(lineNumber) = tline(1);
tline = fgetl(fid);
lineNumber = lineNumber + 1;
end
fclose(fid);
