Degree of a matrix

WebDescription. The degree matrix is the n by n diagonal matrix (where n is the number of vertices in the vertex set of the graph G) indexed by the vertices of G where A_ (u,u) is … WebNilpotent matrix. In linear algebra, a nilpotent matrix is a square matrix N such that. for some positive integer . The smallest such is called the index of , [1] sometimes the degree of . More generally, a nilpotent transformation is a linear transformation of a vector space such that for some positive integer (and thus, for all ).
