The package is really great! However, I would like to know whether it is possible to have some fixed parameter values when using ezfit, eg.
ezfit(x,y,'y(x)=a*x+b')
assuming that I know the actual value of a and want only the fit for b. (Of course if a=3 or some other value I could write ezfit(x,y,'y=3*x+b'), but I want to include this in a script, so a would be a variable...)
