I got the rgb image output but after doing rgb to gray conversion i got null output image. I attached the image for reference. Suggest the way forward.

Did you only do rgb2gray() or did you also do im2double() or perhaps double(), or did you possibly copy the contents of the grayscale image into another array?

I did rgb2gray(). The error was with the code prior to the rgb2gray(), corrected it and got the output also attached the same here. Thanks @ Walter.
