A bunch of changes accumulated over the past half a year again and so it is

time for another release. This is the last release from Wisconsin. Next is

coming from Oklahoma (OSU-Stillwater to be precise), there's just not enough

tornadoes in Wisconsin. The most visible changes in this release are 1)

Using Cairo (having updated to new GtkExtra) so graphs are antialiased on

screen 2) dependent axis can be automatically scaled on line plots (and in

fact does so by default). There are lots of other minor changes and fixes

see below.

 

In any case, Genius is one of the oldest GNOME projects going back to late

1997. It was the original GNOME calculator before I got wild ideas about it

doing absolutely everything. It is programmable, has a powerful language and

handles many fun features including support for matrices, rational numbers,

and nice 2D and 3D plotting. The GUI version requires GNOME2 (at least glib2

if you don't want a GUI) a recent enough GMP library and the MPFR library.

You can still use the command line version if you prefer non-gui interface.

 

Here are the news in 1.0.17:

 

* Better precision for graphs especially when zoomed it a lot, and make font

smaller if needed

* Line plots and parametric plots now allow "fit dependent axis" automatically

when y limits are unspecified. And this is the default in the UI

* Add export of graphs to PDF directly

* Line plot step size is adaptive, also line plots now detect jumps and do not

draw a connecting line, try plotting UnitStep for example

* Use arrow keys to move around a line plot

* left-right arrow keys rotate surface plot

* All plots are now antialiased on the screen (due to GtkExtra update and

cairo usage).

* Update internal GtkExtra to 3.0.5, and forward port all our changes/fixes

(this gets us closer to supporting GTK+3 at some point)

* Completion for "help on function" in the GUI

* Fix FindRootBisection and FindRootMullersMethod

* Factors is now a lot faster on very large numbers (as fast as Factorize)

* Fix placement of labels on surface plots

* A few small fixes and updates to the documentation

* A few minor bugfixes

* Update mersenne primes (new one is known)

* Translation updates (Daniel Mustieles, Marek Èernocký, Dimitris Spingos,

Jiro Matsuzawa, Kjartan Maraas, Martin Srebotnjak, Matej Urbanèiè,

Gil Forcada, Alexandre Franke, Joe Hansen, Miguel Rodríguez)

 

* During making of these changes the author (Jiri) was partially supported by

NSF grant DMS 0900885 and the University of Wisconsin-Madison

Genius is in Ubuntu, Debian, Fedora, GARNOME, OpenSUSE, and probably other

distribution repositories, so check those. Usually you want to install two

packages: genius and gnome-genius (perhaps also gnome-common on some

distros). Of course, it will be a little bit before this version hits those

servers ...

 

Have fun,

 

Jiri
