Huh, expecting others to write your homework? Did you try anything at all?

[Mehmet ali Karatas]

I tried but I still couldn't. I will be glad if you help.

[madhan ravi]

Post what you have tried, even if it has mistakes.

Answer 1

[KSSV]

A = zeros(4) ;
A(1,:) = -20:2:-14 ;
A(2,:) = -12:2:-6 ;
A(3,:) = -4:2:2 ;
A(4,:) = 4:2:10 ;

[Mehmet ali Karatas]

it should form this square matrix with nested loops

Answer 2

[Clement Val]

reshape([-20:2:10], 4, 4)'

Just (half) kidding.

You know how to do a loop?

You know how to index in a 2 dim array?

You know how to increment another variable by two?
