I'v developed the code using padarray and ordfilt2, which satisfies the test suite on my system, but seems like cody doesn't support padarray, is this so??

Hi Dishant, I thought the IPT is available, too, but apparently Cody does not support toolboxes at this time. see box on the right hand side: http://www.mathworks.de/matlabcentral/about/cody/

More difficult thant expected...

Pay attention. The problem is asking for the index and not the value of the steepest gradient. And gradients on diagonals directions must be divided by sqrt(2).
