Re: Quadratic programming
Why sometimes it is impossible to find the solution and what to do with that ?
On 200 iterations with random line and random dots (#10) 81 times QP didnt find the solution (I plot the line and dots for this situations and all looks pretty clear). This is the parameters for QP I use: H = (Y*Y') .* (X*X'); A = Y'; q=1*ones(n,1); b=0; lb=zeros(n,1); (lower bound) ub=[]; (upper bound) min 0.5 x'*H*x + x'*q subject to A*x = b lb <= x <= ub where x is our
