Hello all,
Is it possible to define a path in metapost-metafun using "function"? In
the metafun manual (chapter on Functions) the examples shown are all of
the type "draw function ...". I wonder if it is possible to define a path
with a function ("picture" after draw doesn't allow that afaik)?
there are some helpers in the new graph module, but Alan has to give an
example
% least-squares "fit" to a polynomial
%
% example :
%
% path p[] ;
% numeric a[] ; a0 := 1 ; a1 := .1 ; a2 := .01 ; a3 := .001 ; a4 :=
0.0001 ;
% p0 := makefunctionpath(0,5,10,polynomial_function(a,4,x)) ;
(it fails here so I probably misunderstand it)
