I have a image of 4000*2000 size which is jpeg and two dimensional. I used this image intensity values to get a new image which is of same size (verified by using whos command), but when i m trying to save this new image it is being saved as 250*500 size where as i want it to be of 4000*2000

If your image is 4000x2000 then using imwrite() to save it in jpeg format won't change the size. You must have done something to change the size in advance of calling imwrite(). Show your line of code where you call imwrite() plus a few lines before it, so I can see what you've done. And show the result of the whos command also

@nayana: All we need is the line of code, where you save the matrix as an image. We do not need a copy of imwrite, therefore I have deleted your comment. Before you copy code in the public forum, check for copyright notices in the header.
