How can i put Matlab script in LabView?
I need to recognize some signals from objects but in Lab View I don't have or i don't know how to make that. In this reason i use Matlab tools Neural network but i have doubt about possibility from this.
If somebody solve same or near problems please tell me.
Thank you in advance.
Two ways:
1. Look at the examples of Matlab (in the shipping examples).
2. Do a vi search for "matlab", it will bring up the Matlab script node and you can experiment from there.

Using Matlab script in Labview
Hello,
I am trying to use matlab script in labview to post process the sampled signals from DAQ(attached is the vi I tried)
After every 10 seconds I want to the send the sampled voltage data to matlab scritp block which does 1) detection of peaks using peakdetection function and plots the obtained peaks on the sampled signal 2) calculates standard of 10 secs data and plots on chart.
But I am confused of 1) how to call the peakdetection function inside the matlabscript block
2) How to send the 10secs data of voltage and time values to the matlab script block
3) How to plot the signal and detected peaks on the same plot (which can be done in matlab using holdon as shown in the atached vi).
Can someone suggest for implementing these .
Thanks.

Labview&Matlab.vi 55 KBThanks GabeG,
Now, Labview&Matlab_TestNoAq.vi is woking Good and for the second one Labview&Matlab_TestAq.vi it is showing error as shown in the attached image when these ines of code are present in the matlab scrtip
subplot(2,1,1),plot(maxtab(:,1),maxtab(:,2),'*r');
SDN=std(maxtab(:,1));
and SDN output of the Matlab script
but when I removed these it is working fine(but not showing the detected peaks).
Can you suggest me a solution for the above and also can I know the best method to add one more channel that samples another device signal which has to be processed in this same way(Signals sampled from 2 devices have to be porcessed in this same way).
Thanks.

How can I record a video with LAbview?
Hi,
I have a question: How can I record a video with labview?
I have a camera (AXIS 221) connected via rj45 on PC. I see the video of the camera in a browser.
And I would to acquire the video in labview.
Could someone help me?
Thanks
RafUnfortunately I haven't any experience with this camera. Iguess, you should install API, then crete new VI, place ActiveX container (palette Container->ActiveX) on the Front Panel, then right mouse click, then choose Insert ActiveX object..., then found you camera object and select it and press OK. Then you probably can see image from the on the front panel. Also probably you will be able to get image data in array (how easy is it - depends from the camera API).
If you able to see image from camera in the Internet Explorer, then another method - you can put Microsoft Web Browser as ActiveX object, then you should also see the image. Disadvantage of this method - you will be not able to get image data.

Please!Hi, Trevor

How can I put my podcasts in one place and my music in another?
How can I put my playlists on my NAS media server (Buffalo Linkstation mini) so I can access them through Home Sharing and Sonos?

On Firefox 4, how can I put one "new tab" on the "tab bar" (The + sign) and one next to the "back/forward" buttons (as in FF 3.6)?
In my current Firefox, the "new tab" icon/item from the "customize" pop-up window menu of items is placed next to my home, back, forward buttons near the top-left of my header (Button 1 for "new tab"). Then, the tab bar automatically come with a small tab (with a + sign) to the right of your last tab opened (so you click on + and a new tab opens. Button 2 for "new tab"). I like to have this "new tab" button twice (as a + mini tab, and next to my "home icon".
When I upgraded to Firefox 4, I seemed to be only able to "customize" or use the "new tab" in one place. Either as an icon next to home button, or as a "+ minitab", but NOT both.
What can I do to put this button in Firefox 4 on BOTH places???
Your help is really appreciated. I want to upgrade, but I want my buttons on both places...
I upgraded to FF 4, but downgraded again just because this feature... that's just me of coarse :-)*New tab toolbar button: https://addons.mozilla.org/firefox/addon/new-tab-toolbar-button/

It has always been very basic to always maintain a backup copy of your computer for just such an occasion. Use your backup copy to put everything back.
If for some strange reason you have failed to backup ( not good at all), then you can transfer itunes purchases from an ipod: File>Transfer Purchases
