Matlab Question.

Parameters I have:

A = [2 3 4 1 0 -1 1; 1 2 3 -1 0 1 -1]

r = mean(A)

c = mean(A')

M = repmat(r, 2, 1)

N = repmat(c', 1, 7)

C = A - M

E = A - N

m = zeros(2,size(A,2))

for i = 1:size(A,1)

m = m + A(i,:);

end

m = m/size(A,1)

An m x n matrix of ones is constructed using the command = ones(m, n) Let In be the nx n identify matrix which can be defined in matlab as Zmn In = = eye(n) a) Describe the result of the multiplication F = (Im Zmm -)A m b) Describe the result of the multiplication Znn G = A(In n c) Describe the result of the multiplication Imm Znn H = (Im -) A (In m n An m x n matrix of ones is constructed using the command = ones(m, n) Let In be the nx n identify matrix which can be defined in matlab as Zmn In = = eye(n) a) Describe the result of the multiplication F = (Im Zmm -)A m b) Describe the result of the multiplication Znn G = A(In n c) Describe the result of the multiplication Imm Znn H = (Im -) A (In m n
