Matlab

General information

Version 7.9 (2009b) in the opteron nodes and 7.12 (2010a) in the Xeon nodes. Mathematical program that includes  high-level technical computing language and interactive environment for algorithm development, data visualization, data analysis, and numeric computation.

How to use

Intereactively (with graphical interface):

Matlab is only available for Opteron and Xeon so have to be used interactively from Guinness or Maiz. The graphical interface can be executed with:

matlab

In the queue system

Add the following line in the Torque scripts

/software/bin/matlab < input_file > output_file

where input_file is the file with the matlab commands and output_file is the standar output file name.

With old versions we have had problems with .m files with more than 169 lines. If this happens call your .m program from another small .m program.

To submit the calculation to the nodes add the xeon or the opteron label to submit the calculation to these kink of nodes. In addition, we only have licences to use 2 nodes, so we have the “matlab” special queue to manage them. You must use it. Therefore, your script must contain

#PBS -q matlab
#PBS -l nodes=1:ppn=1:xeon

or for the opteron nodes:

#PBS -q matlab
#PBS -l nodes=1:ppn=1:opteron
