Use pdftops instead of pdf2ps !!!!!

Ubuntu 9.10, Matlab, Mathematica
To install those software packages it is necessary to install first the library ‘libstdc++5’ manually. Since it is not available from Synaptic it is necessary to download it manually.
Additionally, for Matlab, after installing it we have to do
root# cd /usr/loocal/matlab
root# ./install_matlab -glnx
and say yes to all the questions. Then, do (still in /usr/loocal/matlab ):
root# cd bin
root# gedit matlab
and add the following line AFTER the FIRST ONE (#!/bin/sh):
export AWT_TOOLKIT=3DMToolkit
and save the file and exit. Now, you should be able to load Matlab without problems and from anywhere.
3D Plotting Routine for Matlab
A useful function to plot data in Matlab is plot3k which allows you to get 3d scatterplots, important when dealing with real data outputs.
These pictures correspond to the Q and U polarizations of the moon (not to scale) obtained with that routine
Matlab and FFT
Useful link about the implementation of FFT in Matlab.
Also, here they talk about the amplitudes, very useful:

Matlab and Ubuntu
After some time of research, here is how it worked for me:
Install normally following the documentation, even if it doesn’t ask for symbolic links. Then go to the installation directory (/usr/local/matlab in my case):
./install_matlab -glnx
Answer ‘y’ to all questions and keep the suggestions (this takes care of the license stuff). In the same directory as the matlab file (e.g. /usr/local/matlab/bin/) create a file (I called it matlab2 — you can call it matlab2.sh). In this file write
export AWT_TOOLKIT=3DMToolkit
/usr/local/matlab/bin/matlab
Now in the terminal type (still within /usr/local/matlab/bin/)
chmod 755 matlab2
Finally, start Matlab by doing
./matlab2
Matlab 2007 under Fedora 7
Now, trying to install Matlab 2007 under Fedora 7, (as root), I got the following answer:
[root@localhost matlab]# /media/MATHWORKS_R2007A/install &
[1] 4217
[root@localhost matlab]# ——————————————————————-
An error status was returned by the program ‘xsetup’,
the X Window System version of ‘install’. The following
messages were written to standard error:
/media/MATHWORKS_R2007A/update/bin/glnx86/xsetup: error while loading shared libraries: libXp.
so.6: cannot open shared object file: No such file or directory
Attempt to fix the problem and try again. If X is not available
or ‘xsetup’ cannot be made to work then try the terminal
version of ‘install’ using the command:
install* -t or INSTALL* -t
——————————————————————-
Sorry! Setup aborted . . .
The solution was given at http://www.mathworks.com/matlabcentral/newsreader/view_thread/153714, and consists on installing a missing library, right there, as root:
yum install libXp-devel
When finished, try to install Matlab again. It works.
