tool for approximation of condition number
Dear
I need a tool for approximation of condition number of large sparse matrix (performance is important because i deal with transient problem), do you knowe such tool? (note that i knowe that MATLAB perform this but it is very slow and memory intensive so it is not practical for large problem, also i knowe numerical algorithm for this but prepared tool, free from bug, is desired)

I deal with large sparse matrix not full matrix, so application of mentioned package is not practical (it is very time consuming O(n^3)+ O(n^2) and also severly memory intensive).
Have other people better suggestion?

Dear Renato
Do you are certain that SPARSEKIT has such tool, i work with it in previous and don't think there is, but if you knowe more please address related subroutine in SPARSEKIT, with regard. 
Re: tool for approximation of condition number
Sorry... I misunderstood the packages...
Instead of Sparsekit I should have written LINPACK and/or LAPACK. regards Renato.

Thanks Renato,
Althouth i don't get my answer but LINPACK is better than previous suggestion (it estimate condition nummber for full and banded matrixes not for general sparse).
