Hello everybody!
I would like to take advantage of the new construct while (<expr>)
{<commands>} in gnuplot to define a function something like that
f(x,<parameters>,x0 (initial guess of x), eps (maximum error), niter
(maximum no of iterations) =
x=x0;i=1; while (abs(x-x0)>eps && i<niter) {x=some function of x and
parameters;i=i+1}
Obviously I tried and it doesn't work!
The only way I managed to obtained some sensible result is to use the
instruction "call dummy.plt <parameters> x0 eps niter" where
"dummy.plt" script contains the while loop.
However I would like (and I'm not able) to implement such solution as
a user defined function.
I look forward to having your always valued suggestions
Antonio
