"WebThe eigenvalue approach is to find out the solution to an equation in the form of: Mv = λv Where M is an n-by-n input matrix, ‘v’ is a column vector having a length of size ‘n’, and λ is a scalar factor. The values corresponding to λ that satisfy the equation specified in the above form, are counted as eigenvalues. " - Finding eigenvectors in matlab
