Examples of analytic functions include <math> g(z)=\log z=\log(x+iy)</math>, as well as monomials <math> g(z)=z^n=(x+iy)^n</math>, <math> g(z)=z^{n/2}=(x+iy)^{n/2}</math>, where <math> n</math> is an arbitrary positive or negative integer. The monomials <math> g(z)=z^n</math> are also referred to as [[Harmonic functions]] in Computer Vision, and Image Processing.
