ANSWER 8(b): Retriving Ist row of A, and storing it as vector B, Type:

B = [A(1,:)]

ANSWER 8(c): Retriving 3rd column of A, and storing it as vector C, Type:

C = [A(:,3)]

ANSWER 8(d): Retriving rows 3 through 5 and columns 2 through 4 of matrix A, and storing it as vector D, Type:

D = [A(3:5,2:4)]

ANSWER 8(e): Retriving 2nd column and 3rd row of matrix A, and storing it as vector E, Type:

E = vertcat(A(:,2),[A(3,:)].\')
