Hi, How can I implement this problem in python?

thanks

4.3. Least Squares Approximations = 1 = or Suppose B 1,2,4 at times t = -2,0,2. Those times add to zero. The columns of A have zero dot product: C + D(-2) 1 -2 C + D(0) 2 Ax = 1 0 2 D C + D(2) = 4 1 2 Look at the zeros in ATA: AT AT = ATB 30 is 0 8 D 4 = 4.3.
