Build the matrix

The rank of


is

so


is rank deficient. Find the minimal norm solution to the problems

and compute

<sub>i

i</sub>

Explain the results.

Q20:

Show that the

matrix,

in the software distribution is “almost rank deficient.”

Let


^T
and solve the least-squares problem

using normalsolve, qrlstsq, svdlstsq, and rdlstsq. In each case, also compute the residual. Compare the results by filling-in the table.
