I have a code below in which i have error in printing value at the third column
for m3 = 1:(length(dirlist))
I = imread([pathname, dirlist(m3).name]);
A=rgb2gray(I);
A=imresize(A,[256 256]);
J2 = imnoise(A,'salt & pepper',0.2);
Q1=cao(J2);
Q1=imresize(Q1,[256 256]);
Er3= mean2((single(A) - single(Q1)).^2);
error(m3)= mean2((single(A) - single(Q)).^2);
PS(m2) = 20 * log10 (255 / sqrt(Er3));
figure(4),subplot(4,3,m111),imshow(A),title('Original Image')
subplot(4,3,m121),imshow(J2),title('Noise Image')
subplot(4,3,m131),imshow(Q1)
sprintf('Er3 #%d', m131);
m111=m111+3;m121=m121+3;m131=m131+3;
end
I want to print value in Er3 in third column,its not printing ,please help

The code contain a bunch of lines, which do not concern the problem. Posting only the relevant code is more efficient.
Perhaps you mean this line:
sprintf('Er3 #%d', m131);
This creates a string, but does not store it anywhere. Therefore is is useless. Do you mean fprintf to write to the command line? But what does "in third column" mean? Do you want this string to appear as title for the subplot in the 3rd column? Then simply add a title() command and use the sprintf command as argument.

they are just variables used for subplotting

Replace
sprintf('Er3 #%d', m131);
with
title(sprintf('Er3 #%d', m131));
