Make a 20 by 20 matrix in which diagonal elements are 2, 5, 8, 11 ... 59 and the first column is 21,22,23,24 ... 40 whereas the rest of the elements of the matrix are 9.

Note: you must if, elseif, else, end or/and if, end or/and if, else, end commands in MATLAB.

matrix = zeros(20,20);

for i = 1: 20
for j = 1: 20
if j==1
matrix(i,j) = 2*i;
elseif i==1 & j==1
matrix(i,j) = 2;
elseif i==j
matrix(i,j) = matrix(i-1,j-1)+3;
else
matrix(i,j) = 1;
end
end
end
