The Matlab lsqnonlin did the job for me.  It allows some or all of
the coefficients of the model to be constrained.  If very tight bounds
(e.g. +/- 1e-6) are placed on a coefficient, it is the same as fixing
the coefficient to that value.

But thanks to everyone who responded.  I will certainly keep all
the suggestions in mind.  That is the value of this list.  One can
learn a great deal by encountering other perspectives.
