A matrix consisting of
Period random columns which are
repeated (in order) until all columns are filled.
The random numbers are drawn uniformly from (-1,1).
The matrix is rank deficient,
unless the period exceeds the number of columns.
It can lead to underflow problems for Gaussian elimination: see
- This generator is adapted from Nicholas J. Higham's
Test Matrix Toolbox.
