eig

eig calculates the eigenvalues and eigenvectors of a square matrix.

mVal = eig(m)

<cvVal, mVec> = eig(m)

Return Value

cvVal is a complex vector with eigenvalues. mVec is a real or complex matrix with eigenvectors (arranged column wise).

Parameters

m

m is a real or complex square matrix.
