wilkinson Matrix
Description
Generate the Wilkinson matrix of size n x n.The Wilkinson matrix for
testing eigenvalue computations
Usage
wilkinson(n)
Arguments
n
integer
Details
The Wilkinson matrix for testing eigenvalue computations is a symmetric
matrix with three non-zero diagonals and with several pairs of nearly equal
eigenvalues.
Value
matrix of size n x n
Note
The two largest eigenvalues of wilkinson(21) agree to 14, but not 15
decimal places.
