-An '''eigenvalue''' of a square [[matrix]] <math>A</math> is a [[complex number]] <math>\lambda</math> such that
-:<math>A\boldsymbol{x}=\lambda\boldsymbol{x}</math>
-for some non-zero vector <math>\boldsymbol{x}\in\mathbb{R}</math> known as a [[eigenvector]]. The eigenvalue is the zero of a matrix's [[charateristic polynomial]].
-All the eigenvectors of a particular eigenvalue [[span]] a vector space called the [[eigenspace]].
