http://dbpedia.org/ontology/abstract In the mathematical field of linear algebrIn the mathematical field of linear algebra, an arrowhead matrix is a square matrix containing zeros in all entries except for the first row, first column, and main diagonal, these entries can be any number. In other words, the matrix has the form Any symmetric permutation of the arrowhead matrix, , where P is a permutation matrix, is a (permuted) arrowhead matrix. Real symmetric arrowhead matrices are used in some algorithms for finding of eigenvalues and eigenvectors.r finding of eigenvalues and eigenvectors. , Na álgebra linear, uma matriz flecha ou maNa álgebra linear, uma matriz flecha ou matriz ponta de flecha é uma matriz quadrada que contém zeros em todas as entradas, exceto na primeira linha, primeira coluna e diagonal principal, essas entradas podem ser qualquer número. Em outras palavras, a matriz tem a forma Qualquer permutação simétrica da matriz ponta de flecha, , onde é uma matriz de permutação, é uma matriz ponta de flecha (permutada). Matrizes ponta de flecha reais simétricas são usadas em alguns algoritmos para encontrar autovalores e autovetores. para encontrar autovalores e autovetores.
