Why is the subplot not holding the plot ?It just plots the 1st part and does not wait for 2nd to get computed?

clear all;
close all;
aa=imread ('cm.jpg');
%Digital negative-------
figure(1);
subplot (2, 2, 1);
imshow ([255-aa]);
title ('Digital negative of image net');
%Thresholding of image-------
t=input ('Enter threshold value ');
r=double(aa);
[row col]=size(r);
for i=1:1:row
for j=1:1:col
if(r(i,j)>t);
r(i, j)=1;
else
r(i,j)=0;
end
end
end
subplot(2, 2, 2);
imshow(r);

It should wait at this line
t=input ('Enter threshold value ');
for you to enter a number, then continue. That's what it does for me. Are you saying it does not wait for you to enter something in the command window?

Do even see the 'Enter threshold value ' prompt in the command window?
You don't have any m-file of variable also called input, do you? What does this say
>> which -all input
