Estimate X and Y which best fit the following set of equations:
X: n by 1 comlumn vector (unknown)
Y: 1 by 1 unknown constant
Z: n by 1 measured column vector (known)
n is constant and can be as large as expected.
Could you please tell me what method (either numerical or algebra form) I can use to solve the above-mention problem or any suggestion?
THanks a lot.
