Let's break it down so we can see where the error is coming from:
originalImage = imread('divya.pgm')
imshow(originalImage);
imwrite(originalImage,'C:\Users\div\Desktop\myfirstimage.jpg')
Now what happens? Paste all the red error message text - don't paraphrase or cut anything.

Wow - that's really bizarre. That doesn't look anything like your original code, or my code. Are createLightSource(), cut(), and varianceCut() your functions? Or something from some toolbox?
One thing that looks weird is:
G = round(sin(phi) * sum(sum(image(up:down,left:right,2))));
image() is a built in function that takes an image variable and displays it. It's probably getting confused when you pass it two 2-element arrays and a scalar (2). You don't have an image anywhere in your code that you gave the name "image" to, do you? That would be bad. If you do, call your variable something else, like grayImage, originalImage, croppedImage, rgbImage, or something, anything, other than "image".
