MATLAB
Given a 20x20 matrix named G and a 20x1 vector named H, multiply the elements in the 14th column of G by the values in H (element-by-element multiplication, not a multiplication table).

Expert Solution
CODE
function result = doIt(G, H)
for i = 1:20
G(i, 14) *= H(1,14);
end
result = G;
end
G = randi([1 9], [20 20])
H = randi([1 9], [1 20])
result = doIt(G, H)
OUTPUT
G =

In signal processing applications, the Hankel matrix is useful.
The elements of a (N × N) Hankel matrix are given by
h?? =0 ?+?−1>?
=?+?−1 otherwise
Write a script that takes as input from the user an integer, n.
Your code should accept input ≥1 and <10. The user should be
repeatedly prompted until acceptable input is entered. Next, create
n Hankel matrices for N=1,2,...,n. That is, if the user enters 4,
you’ll generate 1×1, 2×2, 3×3, and...
