Module matrix

Makes an n times n hyper-invertible square matrix. The matrix entries will belong to field.

A hyper-invertible matrix is a matrix where every sub-matrix is invertible. A sub-matrix consists of an arbitrary subset of the rows and columns of the original matrix (and is not necessarily a contiguous region).

>>> from field import GF
>>> Zp = GF(47)
>>> print hyper(2, Zp)
[[{46}  {2}]
 [{45}  {3}]]
>>> print hyper(3, Zp)
[[ {1} {44}  {3}]
 [ {3} {39}  {6}]
 [ {6} {32} {10}]]
