Hello every body so I am writing the FCM algorithm in R, but I am wondring
about the efficiency,
When calculating the centers using the formula
where here each X_i is a vector and U_ij are in a matrix,
in other words
I want to multiply each vector in X by a weight and then sum them up and
calculate the mean.
Thank you in advance for your help
