I only need solutions for (d) and (e)

(Use MATLAB when necessary!)

a. Find an associative matrix that will store the stimulus-response pair s1=[0.8 0 -0.6] T1=[1 -1 2 -1] b. Find an associative matrix that will store the stimulus-response pair $2=[0.6 0 0.8] T2=[ 3 1 0 -1] c. Determine whether s1 and $2 are orthonormal. d. Sum the two matrices from parts (a) and (b) and compute the responses of the two stimulus input vectors: $3=[0 1 0] $4=[0.7 0 0.1] e. If the matrix in part (d) is multiplied by any stimulus vector v = [a b c], the result will be the same as for any stimulus vector with the same a and c values, like [a x c]. For example, the input [5 2 1] will give the same response as [5 7 1]. Give an explanation for this in terms. For full credit, include the role of orthogonal vectors in your explanation
