Detailed Description

Very simple example 2.

Generate a Hilbert matrix and work out its eigenvalues and eigenvectors; check result by multiplying out.

The Hilbert matrix is notoriously ill-conditioned (difficult to invert). In this example, I calculate the eigenvalues of a 7 x 7 Hilbert matrix.

The dimensions of this matrix are not large enough for there to be numerical problems but we will be able to see that wide range of values of the eigenvalues.
