what is function to find out adjoint of matrix............is there any command.......

what is command to find adjoint of matrix

Answer 1

[Shashank Prasanna]

I don't think there is a function but you can always do:

det(A)*inv(A)

Answer 2

[asuescun]

Hi, you can't use "det(A)*inv(A)" with a singular matrix to get its adjoint.

Answer 3

[milad yusefi]

you can also use this function function [b]=adj(a) s=size(a); ac=a; if s(1)~=s(2) disp('input matrix must be square') else for i=1:s(1) for j=1:s(2) a(i,:)=[]; a(:,j)=[]; c(i,j)=det(a); a=ac; end end end for i=1:s(1) for j=1:s(2) if mod(i+j,2)==1 c(i,j)=-c(i,j); end end end b=c';
