TOMS726
Orthogonal Polynomials and Quadrature Rules


TOMS726 is a FORTRAN90 library which computes recursion relationships for various families of orthogonal polynomials, as well as the abscissas and weights of related quadrature rules; the library is commonly called ORTHPOL, and is by Walter Gautschi.

Languages:

TOMS726 is available in a FORTRAN90 version.

Related Data and Programs:

TOMS655, a FORTRAN77 library which computes the weights for interpolatory quadrature rules.
