3.1.5. Other packages used by PopRatio

PopRatio uses several routines from the BLAS [15], LAPACK [16] and PPPACK [17] libraries. The routines needed are distributed together with PopRatio in case the user does not have them installed in his/her system.

We use the Fortran 90 interface to the LAPACK routines described by Dongarra et al. [18]. To call the PPPACK routines we have written a new module - SPLINE - containing Fortran 90 interfaces to the routines and a new function that calls them: SPLINE3. The PPPACK routines were slightly modificated in order to support both real and double precision arguments.
