Q1:
On the answer sheet, write the results of the following instructions.
1\ >> a=[2.1 3.7 0;-4.3 1.9 -7.7;-9.2 8.1 3.2]; 9\ >> ans
2\ >> b=[0.2 -3.4 6.7 -5.6]; 10\ >> c(3)=[2 3]
3\ >> a=(:,1:2:3) 11\ >> m=tril(a)+round(a)
4\ >> floor(a) 12\ >> m>b
5\ >> ans(2)=[2 ] 13\ >> linspace(0,12,7)
6\ >> sum(triu(a')) 14\ >> disp('Happy day')
7\ >>c=[-2 0 1;3 2 1;0 1 6]; 15\ >> ans(3)
8\ >> f=a+ceil(a);
