[Insight-users] Ax=b system with CGS

[Ertan Cetingul]

Hi all,

I am trying to solve a system of linear equations Ax=b
using Conjugate Gradient Squared (CGS) method. A is a
sparse matrix by the way. I am using .NET and want to
imitate the MATLAB function "cgs.m" for that purpose.
However I could not find anything apart from vnl_lsqr
and vnl_conjugate_gradient, which takes a
vnl_cost_function F as input. I could not figure out
how to use these.  

I will appreciate any comment.

Best Regards,

Ertan
