Dear all,
I am locking for a quadratic solver in R beeing able to solve the following sort
of problem:
minimize || y - Xmatrix u ||^2
subject to:
Amatrix u <= Bbound and u >= lowbound
While the functions
pcls{mgcv} and solve.QP{quadprog} can handle the first part of the constraint it
seems that they are not designed to deal with the second part (or I do not see
how to specify this second constraint).
Is there an existing function for this sort of problem in R?
Regards,
Sven
