Two implementations of the Givens plane rotations for large and sparse linear least squares problems were discussed in the previous chapter. In the present chapter some pivotal strategies that can successfully be used with the second implementation will

https://doi.org/10.1007/978-1-349-73900-4mation to x = A.b = (A.A).A.b is to be calculated. In this chapter it will be shown that this problem can be transformed into an equivalent problem, which is a system of linear algebraic equations Cy=d whose coefficient matrix C is symmetric and positive definite. Moreover, C can be written as C = D
