compose - a n-ary function with n fields
Compose a n-ary function f with n fields. geo omega ("circle"); space Xh (omega, "P1"); field uh (Xh, 1.0); field vh = interpolate (compose(f,uh)); The compose operator could be used in all non-linear expressions involved in either the interpolate or the integrate functions (see interpolate(4) and integrate(4)). The f function could be either a usual function or a functor.
The compose function supports also the characteristic algorithm (see characteristic(2)) used for convection. characteristic X (-delta_t*uh); test v (Xh); field lh = integrate (compose(uh,X)*v);
The n-arity bases on the variadic template feature of the 2011 c++ normalisation. When this feature is not available, only unary and binary functions are supported.
