HOME WORK (1): Create the following matrices, and use them in the exercises that follow: is $ 22 (12 18 5 21 (a) Create a matrix called d from the third column of matrix a. (b) Co bine matrix b and matrix d to create matrix e, a two- dimensional matrix with three rows and two columns. (c) Combine matrix b and matrix d to create matrix f, a one- dimensional matrix with six rows and one column. (d) Create a matrix g from matrix a and the first three elements of matrix e, with four rows and three columns. (2): For the matrix A=[2 4 -2 9;085 3:1 6 7 0;-46-9 7] execute the following in MATLAB: a) A(3:4,:)= zeros (2,4) b) B= A(3, linspace(1,2,2)) c) C= [ones(2,4):A(2:3,:)]
