Hi,

I have a LINEAR problem that I can solve using \ (slash) operator. I
need to solve a NON_LINEAR version of this problem.

For this I suppose I should use LSQNONLIN. I tried to use it and it
doesn't work.

I then tried for debug to plug into LSQNONLIN my linear problem and
it doesnot work as well.

Do you have an explanation to this?

Thanks a lot for any help
