MATLAB: How to detect the edges in the picture using Robert, Sobel and Prewitt’s operator

Question

Hi, I'm pretty new to Matlab and I need help in the task. It is necessary to apply Robert's, Sobel's and Prewitt's edge detectors to a picture, then interruptions in the contour edges fill and connect the contour.

Any help would be greatly appreciated.

Thank you
