WebOct 19, 2015 · How is it possible to expand a quadratic - let's say NxN - matrix to a bigger on like a (N+k)x(N+k) matrix? It's really all about resizing the matrix and filling the missing rows/columns with zeros such that not dimension mismatch occurs. WebEigenvalues may be equal to zero. We do not consider the zero vector to be an eigenvector: since A 0 = 0 = λ 0 for every scalar λ, the associated eigenvalue would be undefined. If someone hands you a matrix A and a vector v, it is easy to check if v is an eigenvector of A: simply multiply v by A and see if Av is a scalar multiple of v.
