Problem installing Matlab 2007b under Windows 7 64 bits
Dear all, I have issues installing Matlab 2007b under a Windows7 64 bits OS. I use the administrator account of the computer (and right click+ install as the administrator to launch the installation), but at the very begining of the setup (before it even installs anything on the computer), when it just copies some files on the harddrive, I have a message stating that I cannot modify some files without the acknowledgement of "all users"... The files list is: cursors Africa America Antartica Asia Atlantic Australia Etc Europe Indian Pacific SystemV Problem is: it is not written anywhere where those files are located, so I cannot set the security to "enable writing, deleting, etc." or change the ownership of the folder these files are in... Did anyone encounter this problem or have a mean to resolve this issue? I didn't find anything on the forum regarding this particular issue... Thanks a lot! Oh and on a side note, this computer is mine, I installed windows 7 myself 2 days ago (recommended settings all the time,and I didn't change anything since then), and there is and has always been only one account (an administrator one): mine. ...

32-bit Matlab on 64-bit Linux
Hi, I've some mex code(compiled by somebody else on 32-bit machines) but I currently have a 64-bit version of Matlab installed on 64-bit ubuntu. I saw this suggestion from somebody- http://www.mathworks.cn/matlabcentral/newsreader/view_thread/100595 "The fix (since you can't recompile the .mex files) is to run the x86 version of Matlab, which you can install alongside the native x86_64 version. Once you've done that, whenever you need to run your .mexglx files, start Matlab with 'matlab -glnx86'." So I decided to search if this was actually possible and I found two threads from mathworks.com which I personally believe contradict each other with their answers- http://www.mathworks.com/support/solutions/en/data/1-O7POO/ http://www.mathworks.com/support/solutions/en/data/1-1CAT7/ So my question is whether 32-bit matlab can be installed on a 64bit machine ?

Upgrading to 64-Bit DB2 9.7.4 and 64-Bit ooRexx 4.1.0

What is the best way to import Excel files, with stock data, into Matlab? I’m using Matlab R2010b (64-bit)
What is the best way to import Excel files, with stock data, into Matlab? I’m using Matlab R2010b (64-bit) I’m trying to import historical prices of stock data. Matlab keeps cutting off the header of each column; it gives me only values. I am thinking that this is a data-type-mixing-issue, or whatever it’s called. I have ‘Dates’ in ColumnA, and ‘MSFT’, ‘PWER’, ‘KO’, and ‘SBUX’, in ColumnB-ColumnE. Basically, if I put the Excel file in my Matlab folder and double-click the file, I see the values in a matrix (no dates and no headers), I hit ‘Next’. Then, I see only one option; one radio button is enabled – ‘Create variable matching preview’. The other two options, ‘Create vectors from each column using column names’ and ‘Create vectors from each row using row names’ – both are greyed out. I’ve seen videos, on YouTube and on the Matlab site, where people import excel data and these options are NOT greyed out. No matter what I do, there options are ALWAYS greyed out. The problem is, when I click ‘Finish’ in my ‘Workspace’ I have a variable named ‘data’ all values in a 575x4 matrix, but I have NO DATES and I have NO HEADERS on the columns. All of this seems to go into another variable, called ‘textdata’; all dates and headers ate in textdata. This is VERY inconvenient. I’m trying to analyze some stock data and I have no headers, so I have no idea which stock is which (I can figure it out, but I think Matlab should do this for me). Also, I have no dates corresponding to ...

Geodetic functions library GeoDLL 32 Bit and 64 Bit #2 #7
Hi developers, who develops programs with geodetic functionality like world-wide coordinat= e transformations or distance calculations, can use geodetic functions of m= y GeoDLL. The Dynamic Link Library can easily be used with most of the mode= rn programming languages like C, C++, C#, Basic, Delphi, Pascal, Java, Fort= ran, Visual-Objects and others to add geodetic functionality to own applica= tions. For many programming languages =E2=80=8Bappropriate Interfaces are a= vailable. GeoDLL supports 2D and 3D coordinate transformation, geodetic datum shift a= nd reference system convertion with Helmert, Molodenski and NTv2 (e.g. BeTA= 2007, AT_GIS_GRID, CHENYX06), meridian strip changing, user defined coordin= ate and reference systems, distance calculation, Digital Elevation Model, I= NSPIRE support, Direct / Inverse Solutions and a lot of other geodetic func= tions.=20 The DLL is very fast, save and compact because of forceful development in C= ++ with Microsoft Visual Studio 2010. The geodetic functions of the current= version 12.35 are available in 32bit and 64bit architecture. All functions= are prepared for multithreading and server operating.

Multithreading: Different in 64 and 32 Bit Versions of Matlab?
Dear all, I just upgraded to a Windows 7 64 bit box, multicore, 6GB. I installed the 32 bit as well as the 64 bit version of Matlab 2008b (I'm currently stuck with this version). I checked that both versions are actually able to use multithreading using the following code, which led to the use of 4 cores: a = rand(40000,1); for k=1:20000; b=log(a); end Now I let my real world code (pure Matlab) run on both versions: 1.) The 64 bit version make much less use of multithreading. The exact same code runs in the 32 Bit Matlab on 4 cores, and on the 64 bit Matlab only on 1 core. 2.) For some reason, there is not that much of a speed difference. Both Matlab versions take about the same amount of time running that code. The code is complex and it's hard to provide a good minimized example illustrating these effects. But for example, I'm using fmincon, which should gain a lot from multithreading since the computation of the derivatives can be computed in parallel, does not get much slower on the 64 bit Matlab, although it just uses one core. This also holds similarly for other functions I use, for example lsqnonlin. What is going on here? Can somebody tell me more about this behavior? Thanks in advance... What is going on here? I'm having a very similar problem. The 64 bit version of Matlab uses less cores than the 32 Bit version.
