Key Concepts

Eigenvalues

Eigenvalues are scalars associated with a square matrix that indicate how the matrix acts on its eigenvectors. Specifically, when a matrix multiplies one of its eigenvectors, the output is simply the eigenvector scaled by the corresponding eigenvalue. They are found by solving the characteristic equation, which is derived from setting the determinant of (A - ?I) to zero.

Eigenvectors

Eigenvectors are nonzero vectors that change only in scale (and not in direction) when a linear transformation, represented by the matrix, is applied. To find the eigenvectors, one substitutes each eigenvalue into the equation (A - ?I)v = 0 and solves the system for the vector v, often resulting in a subspace corresponding to each eigenvalue.

Characteristic Polynomial

The characteristic polynomial of a matrix is obtained by computing the determinant of (A - ?I), where A is the matrix and I is the identity matrix. The roots of this polynomial are the eigenvalues of the matrix. This polynomial is central to the process of finding eigenvalues and subsequently the eigenvectors.
