pmat4::cross_product Interface Reference

Public Member Functions
real(dp) function, dimension(3)	cross_product_d (a, b)
	Return the cross product of two double precision real 3-vectors.
real(sp) function, dimension(3)	cross_product_s (a, b)
	Return the cross product of two single precision real 3-vectors.
real(dp) function, dimension(4)	triple_cross_product_d (u, v, w)
	Return the triple_cross_product for 4-vectors.
real(sp) function, dimension(4)	triple_cross_product_s (u, v, w)
	Deliver the triple-cross-product, x, of the three 4-vectors, u, v, w, with the sign convention that ordered, {u,v,w,x} form a right-handed quartet in the generic case (determinant >= 0).
