cycol

Returns an <code>n</code>-by-<code>n</code> matrix with cyclically repeating columns
 where one cycle consists of the columns defined by <code>randn(n,k)</code>. Thus, the
 rank of matrix <code>A</code> cannot exceed <code>k</code>, and <code>k</code> must be scalar.

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.
