Skip to content. {\displaystyle i-\,\!} Sea skipping past unwanted data. ) The fundamental fact about diagonalizable maps and matrices is expressed by the following: An matrix over a field is diagonalizable if and only if the sum of the dimensions of its eigenspaces is equal to , which is the case if and only if there exists a basis of consisting of eigenvectors of .If such a basis has been found, one can form the matrix having these basis {\displaystyle \lambda A=0\longrightarrow \lambda =0_{\mathbb {K} }{\text{ o }}A=0}, ( j = Diagonalization can be used to efficiently compute the powers of a matrix 1 de desaparece, la funcin tiene un mnimo local si la matriz de Hessian es definida positiva para todos sus valores.
