circul

Each row is obtained from the previous by cyclically permuting the
 entries one step forward. A special Toeplitz matrix in which diagonals "wrap around"

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.
