It's simply not feasible, i.e. SOS decomposition impossible

Already this fails

solvesos(sos(const2),[],options,[vec(P)',K1,K2,K3])

This is still feasible

solvesos(sos(-expr1(1:3,1:3)),[],options,[vec(P)',K1,K2,K3])

Then add one more row/column

solvesos(sos(-expr1(1:4,1:4)),[],options,[vec(P)',K1,K2,K3])

and it appears to become infeasible (fails massively numerically)

Using only 3 and 4th row

solvesos(sos(-expr1(3:4,3:4)),[],options,[vec(P)',K1,K2,K3])
