Solve system of equations with digamma functions using Newton's method. Equations are

It solves a system of equations like the following:

  1. $\psi(x)-\psi(x+y) = c1$
  2. $\psi(y)-\psi(x+y) = c2$

For newton's method we are using the following iterations:

  1. $\psi(x_new) = \psi(x_old+y_old) + c1$
  2. $\psi(y_new) = \psi(x_old+y_old) + c2$

The script gives the following output:
