# Weighted Network Analysis Book by Steve Horvath, taking the power of a matrix

In Horvath's Weighted network analysis, the author mentions that M^b, where b is a real number and M is a matrix, denotes the element-wise power. This seems odd to me. The way I was taught, M^b would mean multiplying the matrix M, b times. Should element-wise power not be M^(ob) where where o denotes the Hadamard power?
