Hello Everyone. Can please anyone help me about this? I have a text file here that I've already identified which is 'letterabc.txt' and matlab was able to read it and converted it to binary. The said text file has only "ABC" characters inside. What I want to do is to be able to read the characters letter by letter (A->B->C) in a controlled manner. Like its up to the user when will he or she decides to read the next letter(if button is pressed, the user will be able to read the next letter). The characters are already converted to binary (7bits) so I want to be able to read/display (1000001->1000010->1000011) in a controlled manner.

  • int x= 1
  • if x = 1
  • then read next letters % how can I code this part?
  • if x is not 1
  • then steady

fid = fopen('letterabc.txt');
tline = fgetl(fid);
while ischar(tline)
YesOrNo = input('continue Reading [y/n]')
if strcmpi(YesOrNo, 'y')
disp(tline)
tline = fgetl(fid);
else
fclose(fid);
return;
end
