Inom linjär algebra är en idempotent matris en matris som vid multiplicering med sig själv, blir själv igen, dvs =.Notera att för att multiplicering ska vara definierad måste matrisen vara kvadratiskt. An idempotent matrix is a matrix which gives the same matrix if we multiply with the same. Chapter 2 Projection Matrices 2.1 Deflnition Deflnition 2.1 Let x 2 En = V 'W. Then x can be uniquely decomposed into x = x1 +x2 (where x1 2 V and x2 2 W): The transformation that maps x into x1 is called the projection matrix (or Lemma 13. Periodic Matrix: A square matrix is which satisfies the relation A k+1 = A, for some positive integer K, is a periodic matrix. Conversely, if xt Ax <0, for any xnn×1≠0 ×1, A is said to be negative definite.

This video contains the basic of some special type of matrices. 41 Definition 3.1.3 A non-zero vector in ℂ is said to be a -eigen vector of a complex matrix associated with a -eigen value if it satisfies K where K is as defined before. 12.10.2009, 22:15 slater Auf diesen Beitrag antworten » Eine Matrix heißt idempotent wenn A^2 = A*A = A 2. Matrix is said to be nilpotent if A ^m = 0, where m is an integer and 0 is a null matrix. Lets go through one example here. Etymology [ 'I-d&m-"pO-t& ] (adjective.) 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 , 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 ≥). Note that matrix A is said to be Nilpotent if where m is any integer and is a null matrix of same order as of A. If 0 xt Ax > , for any , xnn×1≠0 ×1A is said to be positive definite. bezüglich dieser Verknüpfung.
