A = eye (10)*0.0001; The matrix A has very small entries along the main diagonal.

det uses the LU decomposition to calculate the determinant, which is susceptible to floating-point round-off errors.

Ett vanligt sätt att kontrollera detta är att beräkna determinanten det (A) \text{det}(A) det (A) och kontrollera det den är skild från noll så att det (A) e q 0 \text{det}(A) eq 0 det (A) e q 0. För att beräkna inversmatrisen ska vi därmed skapa en totalmatris med A A A som vänsterled och As another hint, I will take the same matrix, matrix A and take its determinant again but I will do it using a different technique, either technique is valid so here we saying what is the determinant of the 3X3 Matrix A and we can is we can rewrite first two column so first column right over here we could rewrite it as 4 4 -2 and then the second column right over here we could rewrite it -1 5 Alltså den sista determinanten, kan man inte förenkla den/göra den mindre på något sätt eftersom den ser ju nästan identisk ut med ettorna där uppe och där nere till höger, Svaret på den första determinanten ska bli 15, och den andra -4.

Jag får - 1 men svaret ska vara 1.. Har letat efter slarvfel men hittar inget. Den första determinanten kan du t.ex. räkna ut genom att först förenkla genom att multiplicera första raden med -1 och lägga till fjärde.
