This directory contains source codes (Fortran 90/Fortran 95/F)
to test the method of function approximations described in the paper:

"Accurate polynomial interpolations of special functions"
by C. Semay,

working_precision.f90: module to define the working precision

spline_module.f90: module to compute approximations of functions,
                   knowing their first derivatives,
                   and possibly their second derivatives.

func_demo.f90: module containing function definitions
               for the program "test_spline.f"

test_spline.f90: test program for module "spline_module.f",
                 using only the first derivative
                 to compute an approximation.
