Question
Complete the following: Use MATIAB to write a script that solves for w. Define matrix A as [1 2 3; 4 5 6; 7 8 9] and matrix B as [9 8 7; 6 5 4; 3 2 1]. x is equal to the value in the first row and second column of A. y is equal to the value in second row and third column of B. Vector u is equal to the third column of B, and vector v is equal to the second row of A. w is equal to x times u plus y times the transpose of v. Use MATIAB to write a script that solves for C. d is equal to the first row of A and e is equal to the third row of B. C is equal to d times the transpose of e.Explanation / Answer
A=[1 2 3;4 5 6; 7 8 9;];
B=[9 8 7; 6 5 4;3 2 1;];
x=A(1,2);
y=B(2,3);
u=B(:,3);
v=A(2,:);
w=x*u + y*v';
