Calculates eigenvalues and eigenvectors of a symmetric matrix

eigenvalues = cv.eigen(src)
[eigenvalues,eigenvectors,b] = cv.eigen(src)

Input

• src input matrix that must have single or double type, square size and be symmetrical (src' == src).

Output

• eigenvalues output vector of eigenvalues of the same type as src; the eigenvalues are stored in the descending order.
• eigenvectors output matrix of eigenvectors; it has the same size and type as src; the eigenvectors are stored as subsequent matrix rows, in the same order as the corresponding eigenvalues.
• b bool return value

The functions cv.eigen calculate just eigenvalues, or eigenvalues and eigenvectors of the symmetric matrix src:

src*eigenvectors(i,:)' = eigenvalues(i)*eigenvectors(i,:)'
