Abstract
U ovome radu bavit ćemo se Schurovom dekompozicijom kvadratnih matrica te njenim najvažnijim praktičnim primjenama. U prvom dijelu rada navest ćemo neke osnovne pojmove i tvrdnje iz područja linearne algebre koje će nam biti važne za razumijevanje ostatka rada. U drugom dijelu pokazat ćemo egzistenciju Schurove dekompozicije za proizvoljnu kvadratnu matricu, kao i egzistenciju realne Schurove dekompozicije za proizvoljnu realnu kvadratnu matricu. Nakon toga, izgradit ćemo numerički stabilan i učinkovit algoritam za računanje Schurove dekompozicije pod nazivom QR algoritam te ćemo navesti nekoliko ideja za njegovo ubrzanje. U trećem i posljednjem dijelu rada pokazat ćemo neke fundamentalne primjene Schurove dekompozicije, kao što su računanje svojstvenih vrijednosti zadane matrice, računanje nultočaka polinoma proizvoljnog stupnja, računanje matrične eksponencijalne funkcije te rješavanje Ljapunovljevih i Sylvesterovih matričnih jednadžbi.
Abstract (english)
In this paper, we will observe Schur decomposition of square matrices, as well as its most important practical applications. In the first chapter of this paper, we will list some basic terms and statements from the field of linear algebra that will be important during the remaining chapters. In the second chapter, we will show the existence of Schur decomposition for any given square matrix, as well as the existence of real Schur decomposition for any given real square matrix. After that, we will introduce a numerically stable and efficient algorithm used for computing the Schur decomposition called The QR algorithm and we will also list a few ideas we can use to make the algorithm run faster. In the third and the final chapter of this paper, we will show some fundamental applications of Schur decomposition, such as computing the eigenvalues of a given matrix, computing the roots of a polynomial of any degree, computing the matrix exponential function, and solving Lyapunov and Sylvester matrix equations.
