Before asking online about MATLAB functions, read the documentation!

CORRECTION:

The input chosen to become the next center is the one that
generates the hidden node signal that has the smallest
measure of correlation with the target as measured by the
sum of the 4th powers of the input-target correlation
coefficients.
