From 3th Aug 1994: First announcement of Tela
a new freely usable numerical computing environment
Tela (the TEnsor LAnguage) is a numerical computing environment mainly
targeted for numerical simulation pre- and postprocessing work.
- Supports arbitrary dimensional arrays (currently the rank must be less
than five though).
- Is generally 2-4 times faster than Matlab, the extremeties encountered so
far are 0.9-11.
- Has integer, real and complex arrays and scalars.
- Uses HDF format as native save/load format.
- Can also read/write Matlab binary files and some ASCII files.
- No built-in graphics, but uses Kenny Toh's PlotMTV program for plotting.
Graphic is better than in Matlab3.5 but worse than in 4.0.
- Easily extensible in a variety of ways, all of which are not fully
functional in this first public release.
- A program exists for translating Matlab code to Tela. The translation is
not perfect, but must be manually augmented later.
- Others for you to find out ...
How to get it
Anonymous ftp to ftp.funet.fi:pub/sci/math/tela
This is the primary distribution site. Notice that it is in
Finland, Europe. There you can find the source code for Tela itself as well
as for other needed packages. Binary distributions for some systems are
also included (now only SGI, but Linux is coming soon and probably Sun, HP,
What to do with it
If you have a system that is not included in the binary distributions, you
should consider building it yourself from the sources and sending the image
to ftp.funet.fi. Installing Tela from scratch is not difficult, but takes
