I am having trouble finding the minors of a matrix using matlab I currently solved it by hand I just need to check my answers.
I need this in order to solve for the inverse
when solving for the inverse I did...
>> A=[693 -1053 1161; -4606 210 -42; -238 1470 294];
>> B=[20; 4; 65];
>> x=1/-96012*A*B
%where -96012 is my determinant for the original matrix
x =
-0.8865
0.9791
-0.2107
my code worked but I am not sure if that is how you properly solve for the inverse. I solved the minors, cofactors and transpose by hand that is how I got my new matrix
Any suggestions?
Thank you for your time.
