Problem installing Matlab 2007b under Windows 7 64 bitsDear 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 LinuxHi,
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 ?
Thanks

How to tell if a program compiled as 32-bit or 64-bit? (Windows Vista 64) I think I have finally gotten my Visual C++ Express 2008 to
use the 64-bit compiler in the Windows 7 SDK. I THINK! But I want to
make sure. I've compiled some programs with the 'target platform' set
to x64 in VC Express, but how do I tell if they really compiled into
AMD64 code?

if it is a long-running process, you can use CTRL-ALT-DEL to get to task
manager, and see if there is a '*32' by the name (although, verify that
there are some other processes which do have this, to make sure this feature
is present).
alternatively, one can use the CMD shell, and then dumpbin, and see what it
says...
or via "printf("%p\n", &foo);" or similar (x64 if you see 16 hex digits,
rather than 8), not that printf generally only works in console apps though,
and doesn't do anything in GUI apps (nevermind that MSVC++ may complain when
accessing the C API, as MS for whatever reason thought this was a good
idea...).

matlab 32 bit operation 64 bit operation caculation precisionHi
I run matlab programme seperately in 32 bit windows xp operation and 64 bit windows 7 operation ,but find that result is difference. The programme uses fmincon function .In 32 bit ,It can get optimization result ,but in 64 bit , a error occures as follows . I trace caculation process ,and find that It is causes by multiplication

??? Error using ==> svd
Input to SVD must not contain NaN or Inf.
Error in ==> pinv at 29
[U,S,V] = svd(A,0);
First ,What's the reason of the difference. I wonder that maybe it is caused by digit lenght in bit 32 and bit 64.But I'm not sure.
Second, How can I do to get the same result in bit32 and 64 bit . Do I need to control digit length in bit 64 operation .

Upgrading to 64-Bit DB2 9.7.4 and 64-Bit ooRexx 4.1.0I am considering upgrading my server to 64 bit, and have tried finding information regarding 64-bit DB2 and ooRexx, which seems to be very hard to come across.
Can anyone advise some recommendations in this regard ?
IBM's site only discussed 32-bit Rexx and 64-bit DB2 where the API SQLDB2 is no longer supported. See http://publib.boulder.ibm.com/infocenter/db2luw/v9r7/index.jsp?topic=%2Fcom.ibm.db2.luw.apdv.gs.doc%2Fdoc%2Fr0023474.html
No where can I find any information regarding 64-bit ooRexx and DB2, and what is supported. Specifically the Rexx API's SQLEXEC, SQLDBS and SQLDB2.
I do not want to pull the trigger and find all my Rexx Code no longer works.
Many thanks, Fin.

64 bit what? Windows? Linux? Intel? SPARC? IA64? PPC?
ooRexx 4.1.0 builds and works (have not tested DB2) ok on pure 64 bit (not
multilib) Linux on Intel hardware. It will certainly also build and work on
multilib Linux (supporting 32/64 bit).

Please ask more specific questions. Not guaranteed we can help but at least
we'll /know/ whether we can help!

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 ...

Can I do 64-bit gcc compilation on 64-bit RedHat platform ?Hi,
This may seem like a daft question...but can
I actually do 64-bit compilation of Tcl/Tk
with gcc (tcl/tk 8.3.5) ?
The reason I ask is that the configure script
returns the following warning :
"64bit support being disabled -- don't know magic
for this platform"
Looking inside the config script, I don't see
where "-m64" is ever enabled for gcc ?
My system details are:
%> uname -a
Linux
dl145-02
2.4.21-23.ELsmp
x86_64
x86_64
GNU/Linux
RedHat Linux RHEL3 is installed.
The version of gcc is 3.4.3
My tcl source for 8.3.5 is placed
in /usr/sdeacon/tcl
%> cd /usr/sdeacon/tcl/tcl8.3.5/unix
%> ./configure --prefix=/usr/sdeacon/tcl --enable-gcc --enable-shared
--enable-64bit
Thanks in advance for any advice,

I contacted Perforce, and verified with them the Perforce version is indeed 64-bit.
Any advise?
Thank you.
I agree -- I was trying out Perforce 64-bit edition. Matlab says it detects it but will not enable its use. Really strange result. I will be relieved if someone could please offer an explanation.

Server Entr. / Oracle 9.2 - both 64 bit)?

when it's deployed in the 64 bit environment i get:
ORA-06520: PL/SQL: Fejl ved indl=E6sning af eksternt bibliotek
<above is in Danish - sorry about that!>
ORA-06522: Unable to load DLL

Hi Marty,
That's fine. Be sure that any third party libraries you use (Excel, MEX-files, databases, etc.) will run successfully on the Linux cluster. You may need to re-host your applications to run on Linux.
What scheduler are you planning to use?
Do you have a shared file system between Windows and Linux?

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=

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.
PS: Matlab 2009a, Parallel Computing Toolkit is NOT installed
