Sorry about reposting.
I've not received any reply yet,
and I tried several ways, but I couldn't get a clue, either.
So if anyone can help, that would be appreciated.

-------------------------------------------------------------

I've used 'symbolic' calculation in mathematica in many ways,
but this time, 
I wonder if mathematica can solve symbolic matrix operation.
Specifically, 

   m = {{a, b},
        {c, d},
        {e, f}}

   SingluarValues[m]

returns

  SingularValues::"svdf": "SingularValues has received a matrix 
          with infinite precision."

(a,b,c,d,e,f are all symbolics.) 
I need to do several symbolic matrix operations such as SingularValues.
Is there any way to do that?
Thank you.
