Simple matlab code issue

I have an issue with a very basic code using matrices. I had to define 3 matrices and do a few operations. I got them all correct except for the last one. It says the dimensions don't match but that is what the question is telling me to do. Any help would be appreciated.
A=[1,2,3;4,5,6;7,8,9]; %Defining matrices A,B and C B=[2,8,2;1,1,1;7,0,2]; C=[2;0;1]; A+B A.*B transpose(C)*B inv(A)*(C).^1 B+(C).^2
The last one is incorrect and the question asks me to do B+C^2

The quantity (C')*B*inv(A)*(C).^1 is scalar, and B+C.^2 is not correct :
B+(C*C').^2;
is correct

B is a 3x3 matrix and C.^2 is a 3x1 matrix. There's no way you can add them. If you want to square matrix C (i.e. C^2), then C has to be a square matrix as well.
