How do I create an array for the square of numbers from 1 to 100?

This is my code so far:

%Assignment 1 code

%Problem 1

f = f;

a1 = ones(100,1);

a2 = [1:1:100];

a2 = transpose(a2);

A = cat(2,a2,a1);

k = A./f;

%Problem 2

a3 = ????

But i need to make an array that does the following:

Has the first column representing the numbers of 1 to 100 but each is squared (1,4,9,16...10,000), the second is just 1 to 100, and the third is just ones the whole way down.

I already have the second two (Stored in a1 and a1) but I'm not sure how I can create an array that has those squared values outside of typing them all in and I REALLY don't want to do that. Pls help.

a1 = ones(100,1);
%Avoid using the superfluous [], as they are used for concatenation
a2 = (1:100)';

A = [a2.^2 a2 a1]

A = 100×3

1 1 1 4 2 1 9 3 1 16 4 1 25 5 1 36 6 1 49 7 1 64 8 1 81 9 1 100 10 1
