Examples

INTERFACE
MODULE PURE SUBROUTINE LegendreJacobiMatrix(n, D, E, alphaCoeff, betaCoeff)
INTEGER(I4B), INTENT(IN) :: n
!! n should be greater than or equal to 1
REAL(DFP), INTENT(OUT) :: D(:)
!! the size should be 1:n
REAL(DFP), INTENT(OUT) :: E(:)
!! the size should be 1:n-1
REAL(DFP), OPTIONAL, INTENT(OUT) :: alphaCoeff(0:)
!! recurrence coefficient of monic legendre polynomial, from 0 to n-1
REAL(DFP), OPTIONAL, INTENT(OUT) :: betaCoeff(0:)
!! recurrence coefficient of monic legendre polynomial, from 0 to n-1
