Subject:        Matlab as software tool for LSC data analyses?

As we get the DASWG moving forward on outstanding software issues,
I would like the four of you to produce a brief (2-page) report on
Matlab as a tool for large scale analysis of LSC data.  In preparing
the report, I would ask that you consider the following issues:

        1)  Accessibility/cost of matlab to entire collaboration.
        Please include pricing information for any toolboxes needed to
        use compiled matlab, etc, for large scale data analysis.
        
        2)  Platform and other support of compiled matlab.

        3)  Reliability of matlab compilation.
        
        4)  Possibility to hook libraries (e.g. LAL, metaio, etc) into
        matlab to leverage existing code base for LIGO specific issues

        5)  Manpower cost to port, or otherwise hook in, existing
        codes into matlab if it became an approved tool for large
        scale analyses.

I expect that Matlab will remain as a prototyping and post-processing
(graphical) tool.   Your report will be brought to the DASWG for
discussion.   After the broader discussion,  we will bring a
recommendation to the executive committee for adoption at the March
LSC meeting.   

Whatever the outcome of discussions within the DASWG,  I plan to
reconsider all questions relating to software starting in early 2005
when I hope we can start strategic planning for Advanced LIGO data
analysis.

Thanks,
Patrick
