[Gnuplot-info] GNUPLOT: PARAMETERS AND ERRORS

[<ema...@al...>]

I'm Emanuele Di Gloria, a Ubuntu user.=20
I want use gnuplot for my work. I noticed that after every iteration, =
the program gives a value for every parameter used for my function.
For example, i use the function f(x)=3D A+(B*x), with A=3D0 and B=3D3, =
and I have this file, from which I can read the data;


1.0000    3.0000   0   0.002
2.0000    6.0000   0   0.004
3.0000    9.0000   0   0.003
4.0000    12.000   0   0.002
5.0000    15.000   0   0.001
6.0000    18.000   0   0.004
7.0000    21.000   0   0.003
8.0000    24.000   0   0.002
9.0000    27.000   0   0.006

After "interation 5", the program gives=20

A=3D 1,0023e-15
B=3D 1,574e-26  =20

the numbers are invented). What do this two values mean? If they are not =
errors, how can I find errors on A and B? Can you help me?   Thanks.
