Well I was too lazy to do the test you performed, and I didn't find
anything on NI's web site. But I'm nearly certain that the LV
developers have said that transpose is an inplace function at several of
the NIWeek session's I've attended. Maybe that's no longer true or

Hi,
I need an up/down counter, but I can't found it in the Labview libraries (if
exists...)...
So I thought to build one using JK flip flop, but when I try to do the
feedback of the last 2 AND, Labview shows me an error...
How can I do?
Thanks for help...

Using the "Show Buffer Allocations" tool (I forget where I got it on NI's

I am using a DIO-96 for stimulus and response during testing of a PC104
board.
An fpga on the board is preprogrammed to execute part of some of the tests.
The fpga uses some of the DIO signals for input and others for output.
The tests all run okay, EXCEPT, some of them consistently fail if I exit

Yonatan is correct, the LabVIEW RT OS, and I believe most if not all RT
OS's, do not support virtual memory. The simplified reason is that virtual
memory is created through the use of hard drive space which is substantially
slower than RAM. Because of the speed difference, you can easily lose the

While we're on the subject of wish lists, I'd like to propose a more flexible build

I suppose then you could make the case that concatenate is "improperly"
transposed as well.

(at least initially) thinks in rows. I suspect this is based on

I would like to combine array size and index array. So that if I wire a

Hi, LabVIEW users.
I'm having trouble figuring out how to wire-up the Build Waveform VI to a
Matlab Script Node. My goal is to do the following:
Step 1: Use the Multitone Generator to build a Signal
Step 2: Use a Get Waveform Components VI to parse the different elements of
the waveform
Step 3: U
One option would be to create a small VI that would create the
directories for you, build this into an executable and include it with
your distribution.
Then in the App builder dialog, on the Installer Settings tab, hit the
Advanced button, check the Run Executable after installation box and
enter

With more investigation... I've found that my t0 variable on the Build

Matlab code, so my next question is how do I convert a time stamp into a
Real number, namely zero.
