Linear Algebra

Exercise 6.3.22

Answers

As the statement in Theorem 6.13, we may first find a vector $u$ such that $A A^{∗} u = b$ . Finally the minimal solution would be $A^{∗} u$ .

1.: The minimal solution is $(2, 4, - 2)$ .
2.: The minimal solution is $\frac{1}{7} (2, 3, 1)$ .
3.: The minimal solution is $(1,, - \frac{1}{2}, \frac{1}{2})$ .
4.: The minimal solution is $\frac{1}{12} (7, 1, 3, - 1)$ .
