I have Matlab 2010a(64bit) and Maple 15(think 64bit, not sure). When I setup the matlab toolbox, it installs the 32 bit toolbox with maplemex.mex32 file. When I run the code, matlab searches for maplemex.mex64 bit file. Any idea how I can remedy this? I have Visual C++ 2008 Sp1 compiler setup on matlab. Thanks in advance. ...

Long story short, here is the criteria I need. 1) I need two modules running in parallel. One function must activate these two They don't need to START at the same time but both neither return info nor end. They run pretty much infinitely 1.1) I would prefer if the One function also ran separate from the above two in it's own loop but i can deal with a 3'rd function also not ending. 2) I need a shared variable between two of the modules. 1 Module will place information there while the other just reads it, but as they are running parallel. That's it. I can do this in pretty much any other language but matlab I've been having issues with. Problem is I absolutely need to use matlab for one module. If this is impossible to accomplish all in matlab then can i instead run this in C and call one matlab module with separate thread? Sample code below. function mainParallelTest() persistent counter; counter = 0; parfor i=0:2 if (i == 0) ImageProccessorParallelTest(); elseif(i == 1) EventProcessorParallelTest(); elseif(i == 2) prevCounter = 0; tempCounter = 1; while(true) tempCounter = counter; if (tempCounter == prevCounter) %disp('hi') end prevCounter = tempCounter; end end end "Alex Cruikshank" <cruiksam@gmail.com> writes: > Long story short, here is the criteria I need. >...

Hi, I have a question regarding using compiled Matlab executables. I have a compiled Matlab code that runs. When the code runs, it creates a folder inside "T:\Temp\mcrCache7.14". For some reason I have to erase that directory every time I need to run the code, otherwise, it fails. So I wrote a PERL script to call the Matlab executable and to handle the erasing of the directory inside the mcrCache directory. All is well so far. The problem is that now I am running such Matlab compiled code in parallel, and I guess now that creates a problem. Now, the PERL scripts might erase the mcrCache while other PERL script is still running! Questions: 1) I wonder why we even need that mcrCache in the first place. Why can't Matlab just compile an executable that contains everything it needs (self-contained) and that runs locally??? 2) If the mcrCache is something that is needed and I can't take away (see question 1), then how do I handle this problem of running in parallel a compiled Matlab program? Any help in this matter is appreciated. Thanks, Noel Andres ...

It describes the algorithms used in general. Eventually it all ends up in lapack hands at one point or another. For eig, look at the netlib functions to learn more about the implementation. For example, the one for finding eigs for real symmetric matrix is http://www.netlib.org/lapack/single/ssyev.f I have a table here which tells which lapack function is used for which case http://12000.org/my_notes/lapack_analysis/lapack/lapack.htm Different algorithms are used depending on the structure of A.

Hi, I am designing a feedback control loop as part of a project. The MATLAB program reads data through the analog input of a DAC (NI USB 6009), and when there is enough data (say N), it starts to process the data to get a control output and send it through the digital output of the DAC. The reading should be kept going while processing the control signal; and the control signal calculation is refreshed when every time when N/3 data comes in (like a moving window of size N, averaging the old data with the new ones) My problem is how to perform these in parallel? This doesn't need to be in real time, but needs to be fairly quick, the delay still needs to be in orders of seconds. I am not sure if parallel computing toolbox is the solution or there are better (simpler) ways. I am new to Matlab, so please give me some advice on this ^^ thank u all. ...

Hi, I am working on the project with DAQ toolbox of Matlab with NI USB x6336 device. However, I have few progress on it. My problem needs to use trigger, analog input and timer/counter input/ output. More specifically, I use a digital pin to output a 2MHz clock to an external device (counter); for every 100 ms, I will read analog data from the external device, for which I need to send a pulse on another digital pin as read signal (counter and trigger). I have been reading the introduction and related material on DAQ toolbox for couples of days. To get the trigger functionality, I need to use the legacy interface; however, to use the timer/counter, I need the session interface. I am not sure if there is any solution to this problem? Thanks! ...

I'm trying to convert some Matlab code into Fortran 77, as Matlab takes days to solve the multiple finite difference systems I need to solve for. All the Matlab code transfers relatively easily into F77, except for the main solution function (which Matlab makes super easy). I'm not sure if there's some ready-made code I can cut and paste into the F77 program, but essentially I'm trying to substitute for the following line: [V,D]=eig(A,B,'qz') Where Does anyone have any suggestions or advice for how I can implement that in F77?

Hi, This might be a somewhat specific question-- but if anyone has any experience with using the DAQ toolbox with an ADLink DAQ card, any feedback/experience would be appreciated. We have an ADLink PCI-7300A Rev B high-speed digital I/O card. ADLink has released a MATLAB library + adaptor that allows you to use ADLink DAQ cards with MATLAB's DAQ toolbox. We have installed this library, according to the user manual supplied by ADLink. When we check, in MATLAB, to see that the card is recognized, we get the following, >> hwinfo = daqhwinfo hwinfo = ToolboxName: 'Data Acquisition Toolbox' ToolboxVersion: '2.12 (R2008a)' MATLABVersion: '7.6 (R2008a)' InstalledAdaptors: {5x1 cell} >> adqpters =hwinfo.InstalledAdaptors adqpters = 'mcc' 'mwadlink' 'nidaq' 'parallel' 'winsound' >> ADLINK_INFO = daqhwinfo('mwadlink') ADLINK_INFO = AdaptorDllName: 'C:\ADLINK\DAQ-MTLB\DLL\mwADLINK.dll' AdaptorDllVersion: '1, 2, 0, 0' AdaptorName: 'mwadlink' BoardNames: {'PCI-7300'} InstalledBoardIds: {'0'} ObjectConstructorName: {'' '' ''} Clearly, MATLAB recognizes the ADLink adapter. However, it returns an empty array of object constructors... So when we attempt to create a digitalio object (using MATLAB's DAQ to...

... Hello, I have downloaded the C version of the following compression algorithm: http://code.google.com/p/lz4/ They say that it's the fastest, so i have compiled it into a DLL with mingw to use it from FreePascal and Delphi, so i have wrote the interface and all was working perfectly, but when i have benchmarked the parallel LZ4 , that i have wrote, against my Parallel LZO algorithm , i have noticed that they have the almost the same speed on compression and decompression but my Parallel LZO is 7% better on compression ratio than Parallel LZ4 , so i have decided to not include Parallel LZ4 algorithm inside my Parallel Archiver, so if you want to compress Terabytes files i advice you to use my Parallel LZO algorithm with my Parallel Archiver.

First of all, get the original version from the RISCOS Ltd website, not some copy or other. http://support.riscos.com/Support/Updates/index.htm It's a self-extracting archive. You need to follow the instructions, and set the filetype to Absolute, not Archive, then run it. Alternatively, you can load the file into a text editor, delete the first 304 bytes (everything up to the characters 'PK') and save that as a file typed Archive.

Basically, the idea is that stuff specific to a given node will be in its SYS$SPECIFIC directory and stuff common to all nodes (satellites or not) booting from the same system disk will be in SYS$COMMON. A good idea as far as it goes, but does it go far enough? In particular, there are two additional categories, which I'll give the obvious names SYS$CLUSTER and SYS$WORLD. SYS$CLUSTER would include stuff common to all nodes in a cluster, i.e. would differ from SYS$COMMON if there is more than one system disk in the cluster. The obvious place for this stuff is somewhere which is not on ANY system disk. SYS$MANAGER:SYLOGICALS.TEMPLATE provides (at least in newer versions of VMS, starting with 7.2 I believe) a list of at least the most common candidates among VMS system files. Add to this procedures to mount disks in a cluster, SYLOGIN.COM etc. (Obviously, I'm thinking of a cluster where as much as possible is shared.) SYS$WORLD, on the other hand, would include stuff which is common to ALL VMS system disks in the world, e.g. the executables used by VMS itself. Obviously, this should be on EVERY system disk. Put another way, the current SYS$COMMON is a mixture of stuff common to all nodes which boot from that disk, stuff common to all VMS systems in the world and, if the stuff is not located somewhere else (pointed to by logicals in the case of VMS system files), stuff common to all nodes in the cluster (perhaps duplicated on more than one system...
