Detailed Description

template<class Scalar>
class RTOpPack::TOpLinearCombination< Scalar >

Linear combination transformation operator: z0[i] = beta*z0[i].

sum( alpha[k]*v[k][i], k=0...num_vecs-1 ), i=0...n-1.

This transformation operator only accepts num_targ_vec==1 but accepts any num_vecs > 0.

Warning! this class can only be used in SPMD mode and not client/server or master/slave. You know what needs to happen for this to work!
