hanowa

Matrix whose eigenvalues lie on vertical plane in complex plane.
Returns a 2-by-2 block matrix with four <code>n/2</code> by <code>n/2</code> blocks. <code>n</code>
must be an even integer.
<code>[d*eye(m) -diag(1:m),</code>
<code>diag(1:m) d*eye(m)]</code>

Generates a variety of structured test matrices commonly used in numerical linear algebra and computational experiments. Includes well-known matrices for benchmarking and testing the performance, stability, and accuracy of linear algebra algorithms. Inspired by 'MATLAB' 'gallery' functions.
