New functions

  • Posted on April 29, 2009 at 1:32 am

I’ve just added a bundle of new functions to the Symbolic library. These include exp, tan (which needed why weren’t they there already?!), the inverse and hyperbolic trigonometric functions, along with cosec, sec and cot.

The nice thing is that these will automatically get added in to Functy on the next build. Having used the existing functions a fair bit it’s good to have something new to play around with. I’ll try to post some screenshots of my efforts soon.

The updates aren’t in any of the releases yet, so if you want them you’ll need to check out the source from svn.

Some kind of Functy release

Well, after pretty much an entire day of shunting files around the network using more protocols than the EU, I can finally say that there’s a Functy release to show for it.

This is version 0.1, which means it’s a bit brittle and the paint is still drying. It also comes flatpacked, so you’ll have to build it yourself. But if you can get past all of that, it does just about work.

The packages can be downloaded at http://sourceforge.net/projects/functy/

A couple of overlayed circular sin/cosine waves with axes.


Functy is an open source 3D graph drawing package. The emphasis for the application is to allow Cartesian, spherical and parametric curve functions to be plotted and altered quickly and easily. This immediacy and the vivid results are intended to promote fun exploration of 3D functions.
