WebSep 6, 2024 · First you should extract the eigenvalues from the diagonal matrix (mainly for convenience): Theme Copy vLambda = diag (Vect); Then you want the sum of the "first two" for your P_i. Presumably "first two" means the two largest, though that's not made explicitly clear. Let's check where those are: Theme Copy plot (vLambda,'.-') WebIf you attempt to calculate the generalized eigenvalues of the matrix B - 1 A with the command [V,D] = eig (B\A), then MATLAB® returns an error because B\A produces Inf values. Instead, calculate the generalized eigenvalues and right eigenvectors by passing both matrices to the eig function. [V,D] = eig (A,B) V = 2×2 -0.7500 -1.0000 -1.0000 0.5000
