double dblquad_cubature	(	integrand	f,

		double	ay,

		void *	fdata
	)

Functions like Matlab's dblquad() for 2D integrals. Wrapper for cubature by Steven Johnson.

The cubature code is used for double integration. It replaces iterated use of a single-variable adaptive rule as in Matlab's dblquad. cubature.{h|c} by Johnson is based on HIntLib by Rudolf Schuerer as well on GSL itself. cubature is GPLed.
