INVERSE AND ADJOINT OF A MATRIX USING MATLAB

INVERSE OF MATRIX:

matrix inverse can be found out by using the formula

                                               inverse of A = adj(A)/det(A)

adj(A) - adjoint matrix of A

But there is a direct code to find out the Inverse of the matrix

command:
             
               A = [1 4 5; 6 6 8 ; 1 3 7 ]
               B = inv(A)

 the output is

This is how inverse of a matrix can be found.

ADJOINT MATRIX CAN BE FOUND OUT BY

command:  

adj(A) = det(A)*inv(A)

the output is

This is how adjoint matrix can be found
