Fitrst, thanks a lot, now openplot gives me exactly what I want and very
quickly!!!!!!!!!!!!!!!!!
>>By the way it makes an interesting picture -- maybe you
can tell us more about your problem domain.
Well, this program is designed to illustrate the fact that the roots of a
polynomial are continuous (not necesserally derivable) functions of the
coefficients when this coefficients are continuous functions of a real
parameter. (to sum up: every root can be followed continously)
In the program, you define the segment where is the real parametre (with
debut and fin), nb_pts is the number of points you need and eqn_temp(t) is
the polynomial you want to study (t is the real parametre and X is the
indeterminate).
And if you choose to work on [0,1] then [0,2] then [0,3]....... etc. you'll
see the way the roots evolve.
Thanks a lot for answering me so quickly and so well and for maintaining
Maxima
Bye
