1.4. Matritsaviy tenglamani echish

Quyidagi matritsaviy tenglamani undaagi koeffitsent matritsaga teskari matritsa topish bilan echamiz.

Yuqorida keltirilgan formula (*) va (**) formulalar
,
asosida echish uchun oldin ni topamiz va unga B matritsani ko‘paytiramiz. Bu amalni Maple 7 dasturida quyidagicha bajaramiz:
> with(Student[LinearAlgebra]):
> A := <<1,0,1>|<3,1,-1>|<-1,-2,0>>;

> A^-1:=A^(-1);

> B := <<13,2,-2>|<-4,-4,5>|<6,2,5>>;

> X:=A^(-1).B;

1. CHIZIQLI TENGLAMALAR SISITEMACINI ECHISH

Chiziqli tenglamalar sistemasini Gauss, Kramer va teskari matritsa usullari bilan echimini topish masalarini ko‘ramiz.
