So i am having trouble with one of my homework problems..
i am given matrices
A=[1,21,3;5,7,9;11,12,32];B=[2,3,4;5,8,11;8,9,22];C=[2,3,4;7,9,11];
and need to perform the following operations:
inv(A)A*inv(A)A*A'A.*BA.*C %need help here%
%multiplication%
A=[1,21,3;5,7,9;11,12,32];B=[2,3,4;5,8,11;8,9,22];C=[2,3,4;7,9,11];A*B;B*A;A*C;%and here%
C*A%and here%
