Introduction to Matrix Algebra - University of Colorado ...
ibgwww.colorado.eduIn matrix algebra, the inverse of a matrix is that matrix which, when multiplied by the original matrix, gives an identity matrix. The inverse of a matrix is denoted by the superscript “-1”. Hence, AA−1 = A−1A = I A matrix must be square to have an inverse, but not all square matrices have an inverse. In some cases, the inverse does not ...
Chapter 1 Portfolio Theory with Matrix Algebra
faculty.washington.eduThe matrix algebra formulas are easy to translate into matrix programming languages like R. Popular spreadsheet programs like Microsoft Excel, which are the workhorse programs of many financial houses, can also handle basic matrix calculations. All of this makes it worth-while to become familiar with matrix techniques for portfolio calculations.

www.math.drexel.eduLinear Algebra Grinshpan Permutation matrices A permutation matrix is a square matrix obtained from the same size identity matrix by a permutation of rows. Such a matrix is always row equivalent to an identity. Every row and every column of a permutation matrix contain exactly one nonzero entry, which is 1: There are two 2 2 permutation ...
