There is code for that in the Image Processing Toolbox in the edge() function. However if you don't have that and want to try to write your own, then you need to learn how to program MATLAB, and a script is the most basic thing there is. Since you don't know MATLAB yet, try this link: http://www.mathworks.com/matlabcentral/answers/8026-best-way-s-to-master-matlab

Thank You.... Actually i do't have much knowledge in Image processing, so i am unable to start code. Please mention the steps to write my own code in matlab for image gradient. i'm quite familiar with Matlab.
