SQUARE_INTEGRALS
Integrals Over the Interior of the Unit Square in 2D


SQUARE_INTEGRALS is a FORTRAN90 library which returns the exact value of the integral of any monomial over the interior of the unit square in 2D.

The interior of the unit square in 2D is defined by

        0 <= X <= 1,
        0 <= Y <= 1.
      

The integrands are all of the form

        f(x,y) = x^e1 * y^e2
      
where the exponents are nonnegative integers.
