Class xlifepp::DoubleIntgBilinearForm#

class DoubleIntgBilinearForm : public xlifepp::BasicBilinearForm #

describes a bilinear form based on a double integral

intg_domain_v intg_domain_u opu(y) aopu opker(x,y) aopv opv(x) dy dx

with opu, opv: operator on u and v aopu, aopv: algebraic operation (*,|,%,^) opker: operator on a kernel function

note: when kernel = 1 the pointer to kernel function in opker is ker_p=0 ! Be cautious with order of domain, first if for v-domain, second for u-domain

Actually, two ways to handle some integration methods: by pointer to an IntegrationMethod object, so only one integration method (old way, should disappear in futur) by an IntegrationMethods object that handles some IntegrationMethod (new way)
