§6.8 of Numerical Recipes has a routine plgndr for computing the associated Legendre functions of the first kind for integer order and degree.

My question is that can that routine be modified so that it can calculate the associated Legendre functions of the second kind (the logarithmic solutions to the associated Legendre ODE)?

If not, what other strategies can I use?

Thanks in advance.
