Unfortunately there is no built in function for it in Matlab unlike the Fuzzy C-means which already had a built in function (fcm.m). However, there are some useful codes you can start with such as:

Hint: Before going on, you must have a sufficient background on PSO.

Good Luck

Hi Gautam,

in Matworks forum, you have an implementation of the pseudo-code needed to solve your question. I attach you a website with some code. I hope it helps you.

Best,

Thank you Elazab  and Martin sir....i got some clue from the link you referenced.
