input matrix (CV_32FC1 or CV_64FC1 type).
Optionaleigenvalues: Mat
output vector of eigenvalues (type is the same type as src).
Optionaleigenvectors: Mat
output matrix of eigenvectors (type is the same type as src). The eigenvectors are stored as subsequent matrix rows, in the same order as the corresponding eigenvalues. TODO Check binding eigenvalues, eigenvectors was missing
