Polynomial matrices, whose entries are univariate or multivariate polynomials, furnish a powerful algebraic framework for the analysis and control of linear systems. By extending classical matrix ...
Most linear algebra courses start by considering how to solve a system of linear equations. \[ \begin{align} a_{0,0}x_0 + a_{0,1}x_0 + \cdots a_{0,n-1}x_0 & = b_0 ...
Determinants owe their birth to the technique of solving simultaneous linear equations. A large number of physical phenomena are governed by linear differential equations which are solved by reducing ...
