Hi! So I am trying to solve x for M = A^T A och d = A^T b but according to my teacher I should recieve a 3*3 matrix and not a 3*2 matrix. I really don't know what's wrong about my code.
Here are the matrices A and B:

And here is my code:
A = [1 1; 1 2; 1 3; 1 4]
b = [0;3;5;6]
M = A.' *A
d = A.' *b
x = M\d;
disp(x)
Can you see what's wrong?

Kindly post the quesiton in full. The code you gave outputs a 2x1 matrix in 'x' - I couldn't understand what is required instead. Also, what is 'och' in this case?

('och' is Swedish for 'and')
