Mathematics behind the normc function?

Can someone please tell me in simple mathematics how normc is calculated for a matrix like this? I read here and there about it and most just say how it functions in matlab code which I am having a hard time understanding.

0.085686, -6.254676, -8.584638, -24.975258, -18.262936, -9.79049, -3.032068

You divide all components of the vector (v1,v2,v3,...,vn) by sqrt(v1^2+v2^2+v3^2+...+vn^2).
