dorr

Returns a <code>n</code>-by-<code>n</code> row diagonally dominant,
 tridiagonal matrix that is ill-conditioned for small nonnegative values
 of <code>theta</code>. The default value of <code>theta</code> is 0.01.

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.
