I want to normalize an image by dividing the value of each pixel by the square root of the sum of all pixel squares for each image. What will be the code

It's practically just like how it sounds:

denominator = sqrt(sum(yourImage(:).^2));
outputImage = double(yourImage) / denominator;

I trust you were honest when you didn't tag this as homework, because I'm not supposed to just give you the answer if it was your homework. Mark the answer as Accepted once you verify that the code works.
