Hi,
I've got a problem with the command nlsf.constr$ and nlsf.iterate(). It seems
Origin takes into account the constraint if the number of iteration is equal to 1. When I use a larger number of iteration the constraint is just taken into account for the first iteration and not for the others.
Someone can help me ? Thanks

I use the command nlsf.tolerance.
Is there any conflict ?

Remember to clear it before using.

Here's an example:

nlsf.init();
nlsf.begin();
nlsf.func$="boltzmann";
nlsf.y$="draw1_b";
A1=1;
A2=8;
x0=1;
dx=1;
nlsf.constr$="";
nlsf.constr$="A1>1;";
nlsf.iterate(1000);
nlsf.end();
