# Invers matris

Inom linjär algebra har en matris A egenskapen inverterbarhet eller invertibilitet, om och endast om det existerar en matris B sådan att = = där I är enhetsmatrisen.Då kallas A en inverterbar matris och B kallas inversen till A och skrivs A −1.Det följer av definitionen att både A och A −1 är kvadratiska matriser av samma dimension n×n.. Inversen finns hos kvadratiska matriser då bland annat matrisens determinant är skilt från noll. Bestämning av inverser till kvadratiska matriser är jobbigt, och härledningen är mysig - så den lämnar vi och visar bara helt enkelt hur man räknar ut inversen till en 2×2-matris

Deﬁnition 6.20. En kvadratisk matris kallas inverterbar, om det ﬁnns en kvadratisk matris B av samma ordning s˚a att AB = BA= E. Matrisen B kallas i s˚a fall en invers till A. Inversen till matrisen A betecknas A−1. F¨oljande sats visar att en matris kan ha h ¨ogst en invers. Sats 6.21. Om B och C ¨ar inverser till A,s˚a¨ar B = C Matris invers, invers linjär transformation. De-nition. Enhetsmatris I n är kvadratisk matris av storlek n n som har ettor på diagonalen och nollor på alla andra platser, till exempel I 3 = 2 4 1 0 0 0 1 0 0 0 1
