nint_exactness_mixed():
  MATLAB/Octave version 9.11.0.2358333 (R2021b) Update 7

  Investigate the polynomial exactness of
  a multidimensional quadrature rule
  for a region R = R1 x R2 x ... x RM.

  Individual rules may be for:

  Legendre:
  region: [-1,+1]
  weight: w(x)=1
  rules: Gauss-Legendre, Clenshaw-Curtis, Fejer2, Gauss-Patterson

  Jacobi:
  region: [-1,+1]
  weight: w(x)=(1-x)^alpha (1+x)^beta
  rules: Gauss-Jacobi

  Laguerre:
  region: [0,+oo)
  weight: w(x)=exp(-x)
  rules: Gauss-Laguerre

  Generalized Laguerre:
  region: [0,+oo)
  weight: w(x)=x^alpha exp(-x)
  rules: Generalized Gauss-Laguerre

  Hermite:
  region: (-oo,+o)
  weight: w(x)=exp(-x*x)
  rules: Gauss-Hermite

  Generalized Hermite:
  region: (-oo,+oo)
  weight: w(x)=|x|^alpha exp(-x*x)
  rules: generalized Gauss-Hermite
