Detailed Description
template<int dim, int nstate>
class PHiLiP::HyperReduction::AssembleECSWRes< dim, nstate >
Class for assembling NNLS problem (C matrix & d vector from the residual of each snapshot) for finding the weights for the ECSW hyper-reduction approach. NOTE: This class does not solve for the weights, but A and b can be passed to the NNLS solver class.
