array variable as fit parameter?

Show all headers | View raw

Can I directly use an array variable (in 5.1cvs) as a fit parameter,
or is this not (yet) implemented? It'd be highly useful for ploting
a number of datasets along with their fits in one graph.

(Of course i can just use an additional set of regular variables and
function and copy the fit values to an array after each fit.)

set print $data
plot '+' using 1:(sin(1.23*x)*2.34)
set print
array a[3];array b[3]
f(x)= sin(a[i]*x)*b[i]
i=1
# a[i]=1; b[i=2]
fit f(x) $data via a[i],b[i]
