MATLAB: How to use the eig function for nonsymmetric matrices

eig

Hi,
I have a non symmetric matrix and I try to figure out which option of the eig I should use? Thank you

Best Answer

The eig function does not require any additional options for nonsymmetric matrices. There is an example of this in the documentation for eig:
>> A = gallery('circul',3)
A =
       1     2     3
       3     1     2
       2     3     1
>> [V,D] = eig(A);
>> V\A*V % verify that V diagonalizes A
ans =
     6.0000 + 0.0000i   0.0000 - 0.0000i  -0.0000 + 0.0000i
    -0.0000 - 0.0000i  -1.5000 + 0.8660i  -0.0000 - 0.0000i
    -0.0000 + 0.0000i  -0.0000 + 0.0000i  -1.5000 - 0.8660i
