Eigenvector free variable

WebIn other words, an eigenvector is a non-zero characteristic vector (column vector) which changes by a constant factor (which we name "lambda"= \lambda λ) when a square matrix is applied to it through matrix multiplication. Then the eigenvalue is this constant factor, the eigenvalue is \lambda λ . WebSince there are 3 unknowns but only 2 constrants, 3 − 2 =1 of the unknowns, z say, is arbitrary; this is called a free variable. Let z = t, where t is any real number. Back‐substitution of z = t into the second row (− y + 5 z = −6) gives Back substituting z = t and y = 6 + 5 t into the first row ( x + y − 3 z = 4) determines x :

WebIgor Konovalov. 10 years ago. To find the eigenvalues you have to find a characteristic polynomial P which you then have to set equal to zero. So in this case P is equal to (λ-5) (λ+1). Set this to zero and solve for λ. So you get λ-5=0 which gives λ=5 and λ+1=0 which gives λ= -1. 1 comment. WebNotes: 1.
