MatView and ParaView on Ubuntu Touch
====================================

I'm still trying to make my Aquaris M10 tablem more useful. It already have
a Firefox, an OpenOffice, a XFig, the Gimp and few other tools. I can also
run some of my software here (but as I wrote before, the device is a bit
slow for an actual computing).

There is the GNU Octave installed and I use it both for teaching and for
research. And I wanted to be able to export some matrices from the 
Octave in the MatrixMarked format. There are scripts for that but they
were designed for the Matlab and they are not compatible with the
Octave. So I made a very simple export script. It can save non-zero 
members of a dense matrix in the MatrixMarked format. It' s slow (but
not as much as I was initially worried about) but it works.
 
So OK, the first step is done. The next step is a visualization of the matrix.
My tool of choice is the ORNL MatView. It's a nice tool which uses Tcl/Tk up to
8.4. Well, and it is a problem. I wasn't able to make the configure script work
with the Tcl/Tk 8.6 which is available for the stable Ubuntu Touch... :-(

I also use the Paraview for work with large data results. There is even an IRIX
port of this tool. After two hours of compilation it is about 30% done and
there were several errors (I decided to use the version 3.14 because it is
close to the one which I have on the IRIX). Hopefuly I will be able to finish
this.

In meantime I decided to remove two applications from the tablet: the KnownDict
(I often crashes - usually on the second word entered) and the default
Calculator: there is a problem with imposibility to use of a closing bracket
which makes useless all funcions like sin, cos... The dictionary problem I have
resolved with the StarDict program (if uses XMir and does not work without
Bluetooth keyboard). The calculator can be easily replaced with the HP48
emulator (it's quite limited emulation and it - of course - uses RPN notation)
which is enough for now.
