Why in MATLAB when we define A matrix as
A=[1 2 3;4 5 6;7 8 9]
whereas det(A)=0 (determinant(A)=0) , it give us this result for inverse of A:
inv(A)=
ans =
1.0e+016 *
-0.4504 0.9007 -0.4504
0.9007 -1.8014 0.9007
-0.4504 0.9007 -0.4504
why we have inverse when det(A)=0
What kind of algorithm matlab use to define inverse of matrix?
thanks for your attention
