Image processing noise problem

I tried to write the code that will run SaltPepperNoise but I am making an error where can you help if it is not working.

I press run in the editor, but pause is stuck.

x=imread('PEPPERS.TIF');

x=im2double(x);

[row,col]=size(x);

for i=1:row

for j=1:col

N=floor(rand(1000,1000)+0.01)*255;

end

end

subplot(1,2,1)

imshow(x);

title('original');

subplot(1,2,2)

imshow(N);

title('SaltPeperImage');

The variable N inside the loop is changing everytime and finally N is just a number.

To add salt and pepper noise to image, you can use imnoise function.
