Hello all, can some one help me to figure out this :
When the input becomes false, the output becomes false after a preset time delay. The output remains false as long as the input is false.
When the input is true or becomes true, the output is true with no delay.
There is On/Off Delay block available in simulink library, but i would like to have it in matlab code.

delay_to_false = 10;
dc = -1;
while true
insamp = get_input() ;
if ~islogical(insamp); break; end % end of input signalled
if insamp
dc = delay_to_false;
end
dc = dc - 1;
outsamp = dc >= 0;
output_sample(outsamp) ;
end
