Prubeh funkce

[Lubos Kloc]

Dobry den preji,
   Kde ziskat program GNUplot viz. mail pana Mikulika, dole prikladam
strucny popis. Doporucuji, pokud zatim nepouzivate zadny program pro
kresleni grafu. Slibil jsem ale i jine varianty. Ty se hodi, pokud
mate nejaky svuj oblibeny program na kresleni grafu a nechce se Vam
ucit neco jineho. Jedna se o postup, ktery sam pouzivam velice casto.
   Prakticky vsechny kreslici programy (i starsi) umoznuji vystup do
formatu HP-GL. (nekdy ale je tento vystup oznacen jako HP-Plotter 7475
nebo nejak podobne). Pomoci programku HP2TEX pak lze tento format
prevest na format pro prostredi "picture" LaTeXu. HP2TEX je k nalezeni
na ftp://ftp.zcu.cz/pub/tex-archive/support/hp2tex  Tohle vse funguje
v DOSu. Je lepsi v tomto pripade vytvorit obrazek bez popisu
(vektorovy popis pismen v HP-GL je hodne dlouhy) a popisy doplnit
TeXem. K tomu je vhodny program TeXCAD, ktery je soucasti distribuce
CsTeXu.
                                           Zdravi
                                                     Lubos

Ted jeste strucny popis programu GNUplot:
(posta mne prvni pokus vratila, asi to bylo moc dlouhe. Tak jen to
nejdulezitejsi):

Gnuplot is a command-line driven interactive function
plotting utility for UNIX, MSDOS, and VMS platforms.  The software is
copyrighted butfreely distributed (i.e., you don't have to pay for
it).  It wasoriginally intended as graphical program which would allow
scientistsand students to visualize mathematical functions and data.
Gnuplotsupports many different types of terminals, plotters, and
printers(including many color devices, and pseudo-devices like LaTeX)
and iseasily extensible to include new devices.

Gnuplot handles both curves (2 dimensions) and surfaces (3
dimensions). Surfaces can be plotted as a mesh fitting the specified
function, floating in the 3-d coordinate space, or as a contour plot
on the x-y plane. For 2-d plots, there are also many plot styles,
including lines, points, lines with points, error bars, and impulses
(crude bar graphs). Graphs may be labeled with arbitrary labels and
arrows, axes labels, a title, date and time, and a key.  The interface
includes command-line editing and history on most platforms.

                   Where to get updates to GNUPLOT

Congratulations on getting this version of GNUPLOT! Unfortunately, it
may not be the most recent version ("you never know where this version
has been!"). You can be sure that it IS the most recent version by
checking one of the official distribution sites, guaranteed to be kept
up to date (of course, if you got this file from one of those sites,
you don't need to check!).

To hear automatically about future releases (and other GNUPLOT news),
read the newsgroup comp.graphics.gnuplot. Failing that, send mail to
info-gnuplot-request at dartmouth.edu to get on the (equivalent) mailing
list.

At the time of this writing, the following are the official
distribution sites and transfer instructions. Note that
prep.ai.mit.edu is NOT an official site, and may not be up to date.
Also, comp.sources.misc is usually a month or so behind us.

Version: 3.5

In general, GNUPLOT 3.5 is available as the file gnuplot3.5.tar.Z.
There will patches to bring 3.4 to 3.5 as well called gp34to35.shar.Z.
(Version 3.3 was skipped because of possible confusion
with the numerous BETA releases.)  It will be made available to simtel20
and its mirrors in ZIP format, along with a DOS, MS-Windows 3.1 and
OS/2 2.0 executables.

Also, some sites will have gpdoc_ps.zip which contains
PostScript versions of the manuals and tutorials.

Please obtain gnuplot from the site
nearest you.
