# How To Find Eigenvalues And Eigenvectors Of A 4X4 Matrix

How To Find Eigenvalues And Eigenvectors Of A 4X4 Matrix. Any vector v that satisfies t(v)=(lambda)(v) is an eigenvector for the transformation t, and lambda is the eigenvalue that’s associated with the eigenvector v. By expanding along the second column of a − ti, we can obtain the equation.

Though it's time taking process to find the determinant of 4×4 matrix, but the shortcut method is that, you just expand the determinant in that row or column in which the. Eigen() function in r language is used to calculate eigenvalues and eigenvectors of a matrix. It turns out you can use row reduction to find the eigenvalues.
