Overview The MathWorks, Inc. MATLAB MATLAB support for HDF-EOS Examples and demos The MathWorks, Inc. - The Company Founded in 1984, privately held Based in Natick, Massachusetts 475 employees (150+ Developers) Annual growth 30% Founders still active -- Jack Little, Cleve Moler, and Steve Bangert MATLAB MATLAB is the leading computational software for Product design and development Research in industry and academia Technical education Over 400,000 MATLAB users worldwide Used in over 100 countries MATLAB is an integrated technical computing environment. Its capabilities include: Mathematical computation Graphics and visualization Data analysis Algorithm development Simulation and modeling Programming and application development “For the purposes of an engineer or scientist, MATLAB has the most features and is the best developed program in its class.” -IEEE Spectrum, Software Review, February 1997 Aerospace Customers Notable Projects Using MATLAB Space Maneuvering Vehicle Deep Space Probe International Space Station Next Generation Space Telescope “I have been amazed at how MATLAB can boost one’s productivity. Anything from simple analysis to complex modeling and simulation can be done in a fraction of the time it would take to write your own code.” Gregory E. Chamitoff, Ph.D.NASA, Johnson Space Center The MathWorks Products MATLAB HDF-EOS support There is a one-to-one correspondence between HDF-EOS API functions and MATLAB syntaxes. Example: C rid = GDdefboxregion(gid,cornerlon,cornerlat); MATLAB rid = hdfgd(defboxregion,gid,cornerlon,cornerlat); HDF-EOS will be supported in MATLAB 5.3. Examples 15 sample HDF-EOS utilities: What objects are in a file? What does an object contain? Where is the data located? Extracting a Grid region Exporting to a SQL database What objects are in a file? Sample functions GRIDS Names of Grid objects in an HDF-EOS file. SWATHS Names of Swath objects in an HDF-EOS file. POINTS Names of Point objects in an HDF-EOS file. Code fr
