Condition of a linear system

Jasenka Augustinović ; Odjel za matematiku, Sveučilište u Osijeku, Osijek, Hrvatska

Sažetak

This paper provides analysis of condition of a linear system and its connection to the singular value decomposition. It can be seen that ill-conditioned matrices are "nearly singular". The singular value decomposition (SVD) also points to that relationship. In addition, SVD can be used to determine rank and numerical rank of a matrix. These relationships are demonstrated on examples with $3\times3$ matrices, for which Mathematica software package is used.
