LabView 7.1 and MATLAB 7

LabView 7.1 hangs when I try to send variable to MATLAB 7 workspace using
standart LabView to MATLAB script. Nothing appears in MATLAB 7 workspace.
When I tried to run the MATLAB Script-Fractal.vi (MATLAB script node has
only outputs) from examples directory - everything work fine. When I run the
MATLAB Script - Lorenz Diff Eq.vi from examples - error message
appears:"Error 1047 occurred at LabVIEW:  LabVIEW failed to send variable to
the script server. Server:"Inappropriate input array size" in MATLAB
Script - Lorenz Diff Eq.vi". Using LabView 7.1 with previous version of
MATLAB (6.5) I have no problem running examples and my own LabView programs.
Could someone suggest me how to fix described problem?
Regards to All.

I'm having the same difficulties. The only mentioning of this I
found so far was this thread:

Message-ID: <50650000000500000096700100-1079395200000@exchange.ni.com>

referring to this page:


This didn't work for me though. I couldn't get the code working
with Matlab 6.5 (R13SP1) either :-(

Also appreciating any feedback,

Computer games don't affect kids. If Pacman would have affected us as
children, we would now run around in darkened rooms, munching pills
and listening to repetetive music.

Hi all,

Matlab 7.0 (R14) does not work with LabVIEW at this point.  In the
past, a Matlab DLL update was all that was needed to fix communication
problems between LabVIEW and Matlab (<a
300A6NDT</a>).  However, it seems that with Matlab 7.0 (R14),
Mathworks might have changed the way Matlab interfaces with ActiveX
Data Objects (ADOs).  Therefore, LabVIEW does not know how to
communicate with Matlab 7.0.

R&D is fully aware of the situation and is working on a fix.  Until
then, I would suggest rolling back to a previous version of Matlab
that was working with LabVIEW before upgrading to Matlab 7.0.

NI sincerely apologizes for this inconvenience, but we are working
diligently on resolving this issue.

Thank you again for contacting National Instruments.

Thanks for the feedback.

Re: LabView 7.1 and MATLAB 7 #3
LabVIEW 7.1.1 was released around December of 2004, however, if you purchased a new seat of LabVIEW in March 2005, you still would have only received LabVIEW 7.1.&nbsp; The 7.1.1&nbsp;maintenance release&nbsp;was distributed only as a downloadable update to LabVIEW 7.1, not as a full product installer. You can verify which version of LabVIEW you have by selecting "About LabVIEW..." from the Help menu in LabVIEW.&nbsp; Near the lower-right corner of the window that comes up it should show you the version number, i.e. 7.1 or 7.1.1.Message Edited by Jeff B on 04-20-2006 ...

ActiveX error -2147023149 in LabVIEW 7.1 but not LabVIEW 6.1
This is an interesting problem. There is a Tektronics ActiveX control for a TLA700 that works flawlessly in LabVIEW 6.1.

On google I found: -2147023149 == "The authentication service is unknown." A final note is VB and VC++ have no trouble using this control on the same machine. I have searched every possible resource availible and am getting no where on pin pointing where this error could be coming from. Anyone have any ideas or even seen th...
