Family 10

Least squares (paper-only)

These 1 topics share one solution. Spot the family, apply the method — same trick, different story.

Least squares fitting："find the least squares fit" · 给一组数据点拟合 $y=a+bx$ 或 $y=a+bx^2$ · 法方程 $A^TA\mathbf{c}=A^T\mathbf{y}$

The concepts behind this family's method — brush up first if unsure.

orthogonal complement, Gram–Schmidt, projection
