Abstract: In this study, MATLAB program for computing power of an IF matrix, strength of connectedness and index matrix of an IFG and its line IFG have been developed. This has been formulated using the theoretical aspects which are proved in [4]. These programs have been verified with suitable illustrations. The proposed MATLAB program is simple, efficient and takes less computational time in image segmentation. The author hopes that this paper will benefit other researchers who are working in the field image segmentation, fuzzy graph theory and intuitionistic fuzzy graph theory.
