Contact Carl Taswell is working on a wavelet toolbox. The toolbox and associated papers are available via anonymous ftp from simplicity.stanford.edu in /pub/taswell Also, Jeff Kantor is distributing a wavelet toolbox. It is available via anonymous ftp from control.cheg.nd.edu in /pub/wavelets/wavetools1_1.tar The toolbox, rice-wlet-tools-1.1, a collection of MATLAB "mfiles" and "mex" files for twoband and M-band filter bank/wavelet analysis, is available via anonymous ftp from cml.rice.

A.Lotfi has developed a Fuzzy Inference Systems Toolbox. It is available via anonymous ftp from ftp.mathworks.com as /pub/contrib/misc/fuzzy_inference_systems.sh or /pub/contrib/misc/pc_fuzzy_inference_systems.sh A Fuzzy-Control Toolbox has been developed by Bernhard Kaemmpf . Send him email if you are interested in obtaining the software. (Sounds like he is willing to give it away.

Mehmet Zeytinoglu has written a MATLAB toolbox for communications. It is available via anonymous ftp from ftp.mathworks.com as /pub/contrib/misc/comm_tbx.tar

Numeric computation, technical graphics and visualization, and an intuitive programming language for applications in engineering and science MATLAB is a complete environment for high-level programming, as well as interactive data analysis. MATLAB excels at numerical computations, especially when dealing with vectors or matrices of data. Symbolic math is available through an add-on toolbox that uses a Maple kernel. There are too many toolbox add-ons to describe here.

The Mathworks has launched a new website for user-contributed MATLAB files: http://www.matlabcentral.com/ This URL replaces the old FTP site.

When creating a matlab visualizer using matlab 7.0 compiled m-code (any release before 7.4), any figures that you create in MATLAB must have the value visible set to on or they will not be drawn to the screen.

A pipeline or module with a period in its name cannot be called from MATLAB. When you create a pipeline using the GenePattern 3.0 Web Client, the Web Client appends .pipeline to the name. Therefore, pipelines created in the Web Client cannot be called from MATLAB.

MATLAB training MATLAB Central is the key resource for finding helpful tutorials. They also offer many training courses, including e-learning. HIGHLY RECOMMENDED: MATLAB Launchpad, a complete list of video tutorials to help users ramp-up from a standing start. Where to get it MATLAB is available both on computers in the M202 computer lab and on Lane computers for users with a valid SUNetID. First-time users should contact Minmin Qin, computing specialist in M222A, to learn about access.

This is really two questions in one. One is "Can I modify a function's input argument?" This would save memory and simplify programming in some cases. The answer here is "NO". If you modify the input argument of a function, all you do is modify a copy of the argument local to the function.

MATLAB is the name used to refer to the class of matrix calculator environments derived from the first, called MATLAB. MATLAB was developed by Cleve Moler in the late 1970s at the University of New Mexico and other locations with support from the National Science Foundation. Since then, many work-a-likes have been developed or are in development commercially, in government and university labs, and so forth.

There is an IFAC/IEEE-CSS Working Group developing standards and guidelines for these tools. A proposed standard command language was developed, is described in the document "Command Language Standard for CACSD Software" and is available from Magnus Rimvall Control Systems Laboratory, GE-CRD Schenectady, NY 12301

Yes. WRI has developed a free MATLAB-Mathematica interface. It is available via anonymous ftp from mathsource.wri.com as /pub/WhatsNew/matlab2math.tar.Z (Unix) or /pub/WhatsNew/matlab2math.sea.hqx (Mac) or /pub/WhatsNew/matlab2math.zip (Windows) ? or via email via "send 0205-951" to mathsource@wri.com.

There is a list of published book available via anonymous ftp from csi.jpl.nasa.gov as /pub/matlab/matlab-books

Here's the "high-level" summary of the major new additions: * Object-based graphics facility * 3-D color scientific visualization abilities * Animation * Sound output capability * M-file debugging facilities * Low-level file I/O functions * Graphical user interface controls (GUI widget set) * Sparse matrix support * An improved help system * Interpreter and graphics speed improvements * A new External Interface library (MEX-files, engine, MAT-files) * Better documentation (in the eyes of the beh.

This usually happens if in the matlab path you include greater that 4 or 5 paths. One solution is to increase your environment space by adding the following command in your config.sys file: shell=c:\\dos\\command.com /e:nnnnn /p where nnnnn is the number of bytes you use for environment memory. It varies from 256 bytes to 32768 bytes(32Kbytes). Usually, 5000 bytes can solve your problem. (The /p command is used so that the autoexec.bat file runs when you boot your computer.)

Try something like the following in your 'startup.m' file: set(0,'DefaultFigurePosition',[5 5 505 405]) set(0,'DefaultFigureColor',[0,0,0]) %% N.B this has side effects. set(0,'DefaultAxesFontName','times') set(0,'DefaultTextFontName','times') set(0,'DefaultAxesFontSize',12) set(0,'DefaultTextFontSize',12)

Yes, both MatLAB R13 and R14 are available on the non-IA64 nodes. Please see the MatLAB pages for more details. The number of used and available MatLAB licenses can be seen by running: $ /usr/local/pkg/matlab/lmstat -a and the purchase of more licenses can be arranged -- please contact the ACES admins. We ask that users please refrain from unfairly hogging the number of available licenses. On the IA64 (Itanium) nodes and on the all the other nodes, the free Octave software is available.

Michael Robbins started and summarized a great thread on this topic. Michael has graciously allowed me to post his PDF summary here: http://www.mit.edu/~pwb/cssm/GMPP.pdf. Or read the entire thread (all 62 message!) starting with: msgid:<14228c8c.4e06e22f@usw-ex0104-026.remarq.com>. Richard Johnson has recently written a style guide for MATLAB. The advice is not universal, but there are many good points and suggestions. http://www.datatool.com/prod02.

On the PC, you can use the /r flag to start your m-file immediately upon starting MATLAB. Using this in combination with the Windows Task Manager, you can set a MATLAB job to run when you want it to run, even if you are not at the computer. Please note that you will need to exit MATLAB at the end of the m-file. Alternately, if you only want a single file to run, you can name it startup.m and place it in your MATLAB directory.

Caesy' is being developed by Matt Wette (mwette@csi.jpl.nasa.gov) at the Jet Propulsion Laboratory. This will be released to COSMIC soon. It will provide data structures, conversion to C-code, and many other features. See M.Wette, "Caesy: A Computer-Aided Engineering System" Proc. 1992 Symp. on Computer-Aided Control System Design Napa, CA, March 1992 Mat/C' developed at Lawrence Livermore National Laboratories by Don Gavel.

MATLAB's MEX-file facility allows user to use C and Fortran subroutines as MATLAB m-files. It is also possible to use MATLAB as a computational engine for C/Fortran subroutines.

The MATLAB (version 4) print command provides a "-deps" argument which provides a Encapsulated PostScript file of your plot. Some people have reported various problems getting this stuff to work. Some suggestions: Use "bbps" and ghostscript. "bbps.shar" is available via anonymous ftp on "csi.jpl.nasa.gov". You'll need to get GhostScript from your nearest GNU ftp site.

Almost everything in the "demos" directory is not described in the User's Guide. There are lots of goodies there. In 4.0, the demos are best place to see examples of Handle Graphics. There are other undocumented functions in directories other than demos. Some of them are "worker" functions that are unlikely to be used directly; they are simply called by other functions. A few, like COMET and COMET3, were actually written after the User's Guide had been sent to the printer.

A GNU emacs 'matlab-mode' is available via anonymous ftp from csi.jpl.nasa.gov as pub/matlab/util/matlab-mode.el

The FFT in MATLAB is defined as sum(x(i)*exp(-j*i*k/N)) and not sum(x(i)*exp(j*i*k/N)). The first version is traditionally used by engineers, the second version by mathematicians. Since MATLAB was written by an engineer (John Little), the engineering approach was used.
