Markov :: gaussRing

gaussRing -- ring of gaussian correlations on n random variables

Synopsis

Description

The routines gaussMinors (missing documentation), gaussIdeal, gaussTrekIdeal (missing documentation) all require that the ring be created by this function.

i1 : R = gaussRing 5;
i2 : gens R

o2 = {s   , s   , s   , s   , s   , s   , s   , s   , s   , s   , s   , s   ,
       1,1   1,2   1,3   1,4   1,5   2,2   2,3   2,4   2,5   3,3   3,4   3,5 
     ------------------------------------------------------------------------
     s   , s   , s   }
      4,4   4,5   5,5

o2 : List
i3 : genericSymmetricMatrix(R,5)

o3 = | s_(1,1) s_(1,2) s_(1,3) s_(1,4) s_(1,5) |
     | s_(1,2) s_(2,2) s_(2,3) s_(2,4) s_(2,5) |
     | s_(1,3) s_(2,3) s_(3,3) s_(3,4) s_(3,5) |
     | s_(1,4) s_(2,4) s_(3,4) s_(4,4) s_(4,5) |
     | s_(1,5) s_(2,5) s_(3,5) s_(4,5) s_(5,5) |
