MATLAB: Real clock seconds after 1 second delay in input

matlab guimatrix

max = 15
input = [0 0 0 0 1 1 1 0 0 0 1 1 1 1 1]
for i = 1:max
    format shortg
    c = clock
    seconds = c(1,6)
end
% How can I get this input after every one second (one by one)?
% let say when I run my code at that time my clock second is 4.631 second of the clock.
% I mean I want output same like this in matrix formate
input    time (actual seconds from the clock)
  0              4.631
  0              5.631
  0              6.631
  0              7.631
  1              8.631
  1              9.631   
  1             10.631
  0             11.631
  0             12.631
  0             13.631
  1             14.631
  1             15.631
  1             16.631
  1             17.631
  1             18.631
Thank you for your help…

If you do not need high precision on it being every 1.0 seconds elapsed, then:
 max = 15;
input = [0 0 0 0 1 1 1 0 0 0 1 1 1 1 1];
for i = 1:max
c = clock;
seconds = c(1,6);
disp([input(i), seconds])
pause(1)
end
If you do need high precision, then you will need to create a timer() object with fixedRate execution mode
You could also:
 max = 15;
input = [0 0 0 0 1 1 1 0 0 0 1 1 1 1 1];
T = tic;
for i = 1:max
  c = clock;
  seconds = c(1,6);
  disp([input(i), seconds])
  D = i+1-toc(T);
  pause(D)
end
this is a more self-adjusting -- the later it gets in serving an input, the shorter the time it waits.
