👉 In linear algebra, an eigenvector is a vector that changes by a scalar multiple (a scalar exponent) when a matrix in linear algebra is multiplied by it. Eigenvectors are particularly important because they provide a basis for the space of vectors, and they can also be used to represent linear transformations. An eigenvector is typically represented as a column vector (also known as a row vector), with each entry being the eigenvalue associated with that eigenvector. The product of an eig
