I am interested in hearing ideas about the best ways to create "modules" in matlab? The goal is to have one interface, where I can easily switch routines, and have different versions of the routine run. For example, suppose I have a routine to recognize license plates. It needs to be initialized, and then on subsequent calls it needs to be run. Later one, I want to swap the license plate recognition file, with another one, and have the new one take effect. Is there an established 'best practice' for this in Matlab? - Pat [ I'm upgrading to Matlab 2009a, from 2005&...

I was just wondering if somebody knew how to do this. I know of the function gevrnd but have know clue how to generate this. question: In Matlab, create a vector with 10,000 random returns, which follow the generalized extreme value distribution with a mean return of 8% and standard deviation equal to 2.5%. Assume the tail index equals 0.09. Then assume that these are true historical returns. Find the historical simulation VaR figure for a 5% significance level. Then repeat the exercise using normally distributed random numbers and comment on your results. "Hilmar Steindi" <...

Hi All, I used to be able to bring up the helpdesk in a regular browser and view it without having to start matlab (and using up a license). With the new Matlab, all help is pretty little xml files with no stylesheet or dtd information available. Are they docbook or sum such well known format? How does one use the helpsearch.db file? Any help would be appreciated. Regards Satya Satya, The HTML files are compressed to a .jar file and are meant to be run with MATLAB. You can run the MATLAB Editor without starting MATLAB and access Help from there, which doesn't check out a license -...

Please let me know and then we can discuss further. ...

For my project, I need to have a client program (MATLAB executable) talking to a server program (also MATLAB executable) to query data. Is there any easy way to accomplish that? I appreciate any help that I can get on that. Thanks. Cheers, Hoi Oops, I forgot to mention. There are multiple clients querying the server, so I guess serial objects + remote serial port wouldn't work.

Hello, Is there any limitation to run Matlab from Matlab, as a system command, on Linux platforms ? I tried to start Matlab, both using the ! syntax (!matlab&) or the system command (system('matlab&')), the Matlab splash screen appears, but the new Matlab session closes rapidly . When I do the same with a script of mine (system('matlab -r "myscript"&')), my script is being executed, but Matlab finally crashes . If I remove the &, it works well, but the first Matlab session is blocked till I close the second one . I run Matlab on a Linux 64bits pla...

hi. really need help. i've to transmit an image serially between two computers using matlab on both transmitting and receiving ends. i've encoded the image into binary. been facing problems with the transmission when i used the command fprintf. when i executed that, i got a warning saying timeout occurred before terminator was reached. plus the receiving matlab hangs. i was told to save the binary packet into m-files then transmit the file over. how do i do that? is there a command to save and retrieve binary packets into and from m-files? i really need to get this done asap.thank you....

How to determine the delta features from MFCC? can someone please help me out with the matlab codes for it. I am doing my research in this field and have found the formula for delta to be d(t)=[c(t+1)-c(t-1)]/2 where c is the MFCC feature. But if its so then what is the value of d(0) and d(1). ...

Hello, I recently installed matlab 7 and everytime I call the help of an arbitrary function it takes a very long time (> 30s) to show this help (so I mean simply typing for example 'help plot' in matlab command window).

Hi people, I'm having a problem with Matlab (R14). The thing is that I execute Matlab normally in command line: > matlab, but when I try to open the MATLAB Help or another option from menu that shows up in an additional window, matlab crashes. Anyone could help me? Thank you, Talita ...

Hi, I am sure this question has been covered before, but my googling has thus far been fruitless. The installation of matlab 5.3 R11 will complete my migration from windows to Mandrake 10 - I have just installed the libc5 libraries and the appropriate X libs (I think! - matlab no longer complains about missing shared libraries). Now when I run matlab, I get the following: ----------------------------------------------------------------------- Segmentation violation detected at Sat Jul 24 18:26:59 2004 ----------------------------------------------------------------------- ...

Fellow Matlab enthusiast, This is another topic on which I need your help. I am in some ways like you. You regret losing your valuable time before you learnt matlab. I have lost a similar amount of time. I am from the old generate of command line C and unix. Anyway, I learnt C from K&R mainly from the exercises and the micro-manual at the back which identified all the keywords in C and the syntax/grammar of the language. I read it well and it separated the libraries, ie getchar, putchar, printf, scanf, from stdio.h, strings.h, math.h etc. function from the keywords of the C la...

Hello.I'm in desperate need of some help here, I want to import various images of clouds taken about 30 seconds in one another as a single video file the loop I used to originally do this consisted of: files = dir(Directory of files) for i = 1:100 str = strcat('Directory for workspace',files(i).name); clouds(i,:,:,:)=imread(str); end; But the images it produced were 4-d uint 8 and i was unable to read them or work with them at all. Please can you offer me some type of solution. The main goal of these processed cloud images is to be able to track the movement of clouds in t...

Hello everyone, How do I compile MATLAB M files into a form that can then be called from within the MATLAB interpreter? A roundabout way would seem to be to (somehow) Turn the matlab code into C (I think mcc does this), then compile this C code into MEX format and call that. Is there an easier way? I have the MATLAB compiler, so I just need to know what to do with it to get this to work.

Hi guys I am now experencing a great difficulty in the interation between java and matlab. I have an objective function written in JAVA with has method return an numerical number, i call it 'profit'. The nature of this obtive function (ObjFun.java) is that it takes an parameter input, say C, with different C value, the returned profit value is different. Eventually I want to find the optimized C value which produce the maximun profit (C will be under constrains). Initially I want to use linprog or fminsearch in matlab. So I tried the command in matlab that excutes my ObjFun.ja...

Hi I have two win PCs running matlab 7. One is slow and other is a high spec fast PC. They are connected to LAN. The directory on fast PC where all matlab work takes place has been mounted as a drive on slow PC. Hence this directory on fast PC can be accessed from slow PC's matlab session. I want to let the user on slow PC run some computationally intense M scripts in his matlab session but execute them on fast PC. I tried usual unix like method. First installed telnet server on fast PC. Then used telnet client on slow PC to log on fast PC. If I attempt to start matlab in slow PC telnet ...

Hi. There is a dicussion going on here about whether or not it is sensible to have a module on Matlab in the first or second year of a computer science BSc degree. It's not me proposing the module. Some people are arguing that since Matlab is a full programming language, that a full module is justified. Other people are arguing that since it is just a "software system" it would be like having a degree level module in Microsoft Word. Are there examples of universities teaching degree level modules in Matlab? Also, since Matlab is commercial (and expensive) software, that student...
