eig

Eigenvalue Function (Matlab Style)

Eigenvalues of a matrix

eig(a)

`a`	real or complex square matrix

Computes the eigenvalues of a square matrix of real or complex numbers, using the R routine eigen without computing the eigenvectors.

Vector of eigenvalues

eig(matrix(c(1,-1,-1,1), 2, 2))   #=> 2 0
  eig(matrix(c(1,1,-1,1), 2, 2))    # complex values
  eig(matrix(c(0,1i,-1i,0), 2, 2))  # real values
