     Similarity invariants
       
  a) Verify with numeric applications,

          * B is similar to A.   
          * B is similar to A, also A is similar to B.  

          * A and invPAP have the same determinant.
          * A is invertible if and only, if invPAP is invertible.  
          * A and invPAP have the same rank.
          * A and invPAP have the same nullity.
          * A and invPAP have the same trace.
          * A and invPAP have the same, characteristic equation. 
          * The eigenvector of invPAP.

          * B is similar to A, TrpsB and TrpsA are similar.

      I have used gcc.2.9 (Dev-C++ 4), 
                  gcc.3.2 (v2DJGPP Rhide).
