diagonalization of matrices induced by resolutions of the unit matrix into the sum of idempotent matrices. We show that the block diagonal matrices have disjoint spectra if and only if each idempotent matrix in the inducing resolution double commutes with the given matrix. Applications include a new characterization of an eigenprojection and of the Drazin inverse of a given matrix. Keywords : eigenprojection‚ resolutions of the unit matrix‚ block diagonalization MSC 2000 : 15A21‚ 15A27‚ 15A18‚ 15A09

All rights reserved. Matrices Matrices are classified in terms of the numbers of rows and columns they have. Matrix M has three rows and four columns‚ so we say this is a 3 4 (read “three by four”) matrix. 2 Matrices The matrix has m rows and n columns‚ so it is an m n matrix. When we designate A as an m n matrix‚ we are indicating the size of the matrix. 3 Matrices Two matrices are said to have the same order (be the same size) if they have the same number of

Perceptions of Reality in The Matrix Student: Jyl Alampay Student Number: 250431312 Section: 002 Due Date: December 02/09 The question of ‘reality’ has always intrigued people throughout the world. It has been perceived as tangible and exact but at the same time intensely vulnerable. The frailties of ‘reality’ have been exposed by the many differing ways in which it can be perceived. These differences of perception can be attributed to factors such as age‚ sex‚ nationality‚ religion‚ and

think of a matrix as being made up of 1 or more row vectors of equal length. Equivalently‚ you can think of a matrix of being made up of 1 or more column vectors of equal length. Consider‚ for example‚ the matrix 1 2 3 0 A = 5 −1 0 0 . 3 −2 5 0 One could say that the matrix A is made up of 3 rows of length 4. Equivalently‚ one could say that matrix A is made up of 4 columns of length 3. In either model‚ we have 3 rows and 4 columns. We will say that the dimensions of the matrix are 3-by-4
