jordanForm -- Jordan canonical form

Synopsis

Description

i1 : R = QQ[x,y,z]

o1 = R

o1 : PolynomialRing
i2 : A = matrix{{1,2},{-1,3}}

o2 = | 1  2 |
     | -1 3 |

              2        2
o2 : Matrix ZZ  <--- ZZ
i3 : (pCh,sepEigs,peigs,palgm,JF) = jordanForm(A)

o3 = (| .816497          .816497          |, {| .816497          |, |
      | .408248+.408248i .408248-.408248i |   | .408248+.408248i |  |
     ------------------------------------------------------------------------
     .816497          |}, {2+ii, 2-ii}, {1, 1}, | 2+i 0   |)
     .408248-.408248i |                         | 0   2-i |

o3 : Sequence

Caveat

the procedure involves computation over inexact field and hence the results may be not reliable.
