A Creat a Matrix B using submatrices made up of elementary m

A) Creat a Matrix B using submatrices made up of elementary matrices: one, zeros and identity matrix of the special sizes

B) Show the diagonal of Matrix B in a row vector without the transpose

(C) Using Matlab. Create vectors C, C1, and C2 of length 4, 3, 2 respectively.

(D) Using Matlab. Create Matrix C use part (C) by putting d on the main diagonal, C1 on the first upper diagonal and C2 on the second lower diagonal.

Solution

submatrix1 = ones(3,2);
submatrix2 = zeros(2,5);
submatrix3 = eye(3);
B = horzcat(submatrix1, submatrix3);
B = vertcat(B, submatrix2)
diag = [];
for i=1:size(B,1)
    for j=1:size(B,2)
        if i==j
            diag(end+1) = B(i,j);
        end
    end
end
disp(diag);

C = zeros(4,1);
C1 = zeros(3,1);
C2 = zeros(2,1);
