I want to solve a linear equation Ax= b, using least-squares. I also need to find the error in the solution. I am not sure how to find the error.
Error is;
𝐸=‖𝐴𝒙−𝒃‖^2 =Σ𝜃𝑖^2 where i is index counter
A=[2 0;3 1;4 3];
b=[2;3;4];
x= A\b;
I am not sure how to calculate the error. Can someone help me?

x= A\b;
E=norm(A*x-b)^2
