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.

Hi Dushyant,

You can try to use TLSQR for sparse cases on LSSOL for dense cases in
TOMLAB.

Best wishes, Marcus

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.
