I’m using the function polyeig to solve a quadratic eigenvalue problem with complex matrices A0.A1 and A2 (A2 is singular; has only two non-zero rows).
The result was so bad, and according to the help center of Mathworks : (Scaling A0,A1,…,Ap to have norm(Ai) roughly equal to 1 might increase the accuracy of polyeig)

Is there any function in Matlab to do this scaling?
