Yes, we've been getting a bunch of spam about Separable Nonlinear Least
Squares.

Your posts are not getting lost in the mix.

You picked a weekend. Have you ever done a historical analysis of who
tends to answer posts on weekends, and of what kinds of posts that
person tends to answer?

The people who tend to answer more than the occasional weekend post,
tend to include myself, ImageAnalyst, John D'Errico, TideMan, Greg
Heath, and Urs; Rune, Bruno, dbp, and Roger Stafford often show up on
weekends, but with perceptibly reduced posting volume compared to the
weekday.

Of those, the ones who tend to deal with issues such as your present
topic are John and occasionally Roger (if the question happens to spark
his interest; he is more likely to deal with geometry and algebra
questions.) TideMan has some fitting experience as well, but prefers to
concentrate on varieties of fitting quite different from what you raise,
such as fitting functions to data or fitting with wavelets.

It is rumoured that John has a Time-Share on a Life, that he sometimes
uses on weekends. I send off for a Life from Nigeria, but it's been
caught in paperwork and various customs fees for the last 8 years, and I
don't know when it will arrive.

If you are expecting TMW to respond, then start a support case with TMW.
Any Mathworks employees that visit here do so as volunteers.
