From: Dushyant on 25 May 2010 14:50 lsqnonneg works fine and returns resnorm of 9 10^-8 while lsqlin returns peaky solution and the resnorm of 1.12 10^-5. The returned solution in this case is ok, not as good as in the case of lsqnonneg. Since the problem is large scale, I am under impression that I can not use lsqnonneg. I would like to use lsqlin.

From: Dushyant on 25 May 2010 15:28 Any Response ... My problem is: I am not able to make "lsqlin" run till lower value of "resnorm" is obtained (from 10^-5 to say 10^-8). I think that I am not able to set the options.
