Finds the eigenvalues and right eigenvectors of the square Input Matrix. Wire data to the Input Matrix input to determine the polymorphic instance to use or manually select the instance.

Real
The eigenvalue problem is to determine the nontrivial solutions to the equation:
AX = λXwhere A is an n-by-n Input Matrix, X is a vector with n elements, and λ is a scalar. The n values of λ that satisfy the equation are the Eigenvalues of A and the corresponding values of X are the right Eigenvectors of A. A real, symmetric matrix always has real eigenvalues and eigenvectors. This VI returns the real eigenvalues in ascending order if the Input Matrix is a real symmetric matrix.
Complex
The eigenvalue problem is to determine the nontrivial solutions for the equation:
AX = λXwhere A represents an n-by-n Input Matrix, X represents a vector with n elements, and λ is a scalar. The n values of λ that satisfy the equation are the Eigenvalues of A and the corresponding values of X are the right Eigenvectors of A. A Hermitian matrix always has real eigenvalues. This VI returns the real eigenvalues in ascending order if the Input Matrix is a Hermitian matrix.
