double cpv ( double f ( double x ), double a, double b, int n )

//****************************************************************************80
//
//  Purpose:
//
//    CPV estimates the Cauchy Principal Value of an integral.
//
//  Location:
//
//    http://people.sc.fsu.edu/~jburkardt/c_src/cauchy_principal_value/cpv.c
//
//  Discussion:
//
//    This function can be used to estimate the Cauchy Principal Value of
//    a singular integral of the form 
//      Integral f(t)/(t-x) dt 
//    over an interval which includes the singularity point t=x.
//
//    Isolate the singularity at x in a symmetric interval of finite size delta:
//
//        CPV ( Integral ( a         <= t <= b         ) p(t) / ( t - x ) dt )
//      =       Integral ( a         <= t <= x - delta ) p(t) / ( t - x ) dt
//      + CPV ( Integral ( x - delta <= t <= x + delta ) p(t) / ( t - x ) dt )
//      +       Integral ( x + delta <= t <= b         ) p(t) / ( t - x ) dt.
//
//    We assume the first and third integrals can be handled in the usual way.
//    The second integral can be rewritten as
//      Integral ( -1 <= s <= +1 ) ( p(s*delta+x) - p(x) ) / s ds
//    and approximated by
//      Sum ( 1 <= i <= N ) w(i) * ( p(xi*delta+x) - p(x) ) / xi(i)
//    = Sum ( 1 <= i <= N ) w(i) * ( p(xi*delta+x) ) / xi(i)
//    if we assume that N is even, so that coefficients of p(x) sum to zero.

//  Purpose:
//
//    LEGENDRE_SET sets abscissas and weights for Gauss-Legendre quadrature.

//
//    The integral:
//
//      Integral ( -1 <= X <= 1 ) F(X) dX
//
//    Quadrature rule:
//
//      Sum ( 1 <= I <= N ) W(I) * F ( X(I) )
//
//    The quadrature rule is exact for all polynomials through degree 2*N-1.
//
//    The abscissas are the zeroes of the Legendre polynomial P(N)(X).
//
//    Mathematica can compute the abscissas and weights of a Gauss-Legendre
//    rule of order N for the interval [A,B] with P digits of precision
