How to interface the Labview and Simulink (Matlab) without using the "NI LabVIEW Simulation Interface Toolkit"?

I've been using the Labview for the data aquisition. And I also developed a controller in the Simulink (Matlab) environment. I'd like to control my application using both programs. How could I interface the Labview and Simulink (Matlab) without using the "NI LabVIEW Simulation Interface Toolkit"?
thank you,

Thank you for posting to the National Instruments Discussion

If you are not using the Math Interface Toolkit, you may be
interested in using the MATLAB�  Script Node. This allows
you to call MATLAB�  commands using ActiveX and I you
can call your Simulink model from MATLAB�  that way.

Here are some resources on how you can do this:

Hi, Abhinav,
thank you for your reply. I will try to explore the option with the Script Node.

Adding an &quot;IMAQ Image.ctl&quot; to the &quot;Display State.ctl&quot; of an XControl prevents LabVIEW from creating a probe of &quot;Display State.ctl&quot;
I am working on an extended IMAQ Display control using LabVIEWs XControl capabilities. &nbsp; I need a copy of the original image passed to add some overlays which must not affect the original image. To achieve this I am creating a backup image in the "Init.vi" and deleting it in the "Uninit.vi". I am storing the reference&nbsp;of this image&nbsp;in the "Display State.ctl" which is part of every XControl. &nbsp; As soon as I am adding an "IMAQ Image.ctl" to the Display State cluster, it is no longer possible to generate a probe of the Display State cluster for debugging purposses. I am always getting the message: "Failed to load or create probe." Deleting the "IMAQ Image.ctl" from the cluster makes the probe working again. &nbsp; Is it a bug or am I doing something wrong? &nbsp; I am working with LabVIEW 8.5 and Vision 8.5. &nbsp; Regards &nbsp; Ingo Bartsch Hello Mr. Bartsch, is it possible for you to post a small example to reproduce the behaviour?

How can I modify the &quot;Type definitions&quot; of &quot;Function Prototype&quot; if I want build a DLL in Labview 8.5.1.?
Hello,We have a library with several VIs (API - Interfaces to our Real Time Target). This VIs we provide to our customer to generate own VIs to control the Real Time Target.Now we want to provide the functionality of this VI-library as DLL to our customer. The problem is, that labview use self definite name of type definitions. Also if I use "strict Type definition".Example:void GetOutputValues(VARIANT *Scale_In, int32_t ModelNr, uint16_t SignalID[], TD1:smileymad: *errorIn, VARIANT *Scale_Out, TD2 *Data, TD1 *errorOut, int32_t len)It is possible to modify "TD1" and "TD2"? I want to give useful names.GreetingsSteffen Hi Steffen, &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Try&nbsp;editing the .h file as follows: CHANGE FROM: typedef struct {&nbsp;LVBoolean status;&nbsp;long code;&nbsp;LStrHandle source;&nbsp;} TD1; CHANGE TO: typedef struct {&nbsp;LVBoolean status;&nbsp;long code;&nbsp;LStrHandle source;&nbsp;} TD1; typedef struct {&nbsp;LVBoolean status;&nbsp;long code;&nbsp;LStrHandle source;&nbsp;} LVErrorCluster; then your GetOutputValues prototype becomes: void GetOutputValues(VARIANT *Scale_In, int32_t ModelNr, uint16_t SignalID[], LVErrorCluster *errorIn, VARIANT *Scale_Out, TD2 *Data, LVErrorCluster *errorOut, int32_t len) If your source-code doesn't refer to "TD1", then&nbsp;you probably won't need to keep the TD1 prototype!

How can I convert the &quot;AI one pt&quot; symbol from LabVIEW 6.3 to LabVIEW 8.0?
Hi, &nbsp; I've got an assignment with LabVIEW and&nbsp;I work with LabVIEW 8.0. The program I work with is written in LabVIEW 6.3 and had to be converted&nbsp;to LabVIEW 8.0. That went very well, except for one symbol. The "AI one pt" symbol (see&nbsp;enclosed figure) turned into an empty box (question mark). My question to you is how can I overcome this problem, or how can I simulate this symbol with LabVIEW 8.0? &nbsp; With kind regards, &nbsp; Sander Smeets &nbsp; <img src="http://www.ese.upenn.edu/rca/software/Labview/labview41/inputoutput/AISamplechannel.gif"> Hello, Graziano is right about this. To make it completly clear: The block you refer to as a symbol is a VI belonging to the Traditional NI-DAQ driver. Currently there are two drivers for DAQ boards: DAQmx (the new one) and Traditional NI-DAQ (the old one). Since your VI was written in LabVIEW 6.x (6.3 never existed) the VI uses the old driver. What you need to do is: install Traditional NI-DAQ on your PC to get the support VI's for the driver in LabVIEW. This Traditional NI-DAQ installer&nbsp;should be on the driver CD which was delivered along with LabVIEW 8.0 or you can download it here: <a href="http://joule.ni.com/nidu/cds/view/p/id/586/lang/en" target="_blank">http://joule.ni.com/nidu/cds/view/p/id/586/lang/en</a> There is one good point though which Graziano already mentioned: Which DAQ board are you using?

Looking for a LabVIEW &quot;Comparison Tool&quot;
&nbsp; LabVIEW is hell to debug. &nbsp; I'm working through Exercise 7-5&nbsp;in the Intermediate I Course Manual. There is a Producer Loop, a Consumer Loop, and a Display Loop, each with a 8 to 12 element Case Structure. &nbsp; Currently (11/14/2007), my project bombs consistently. Press Play, let it get half way through its cycle, press Stop, then the interface becomes unresponsive. I've tried enabling Highlight Execution, but there are many VIs that&nbsp;I&nbsp;don't understand (the manual has me drop them in) and&nbsp;so many things going on at once that I am lost. &nbsp; I&nbsp;navigated to&nbsp;the Solutions folder, and opened the project. The solution (from what I can see) looks identical to mine, and it runs as it should. &nbsp; I want to compare the two, so I tried to open another instance of LabVIEW so that I could look at each of the cases side-by-side. Naturally, LabSPEW (as we have come to call it) will not let you open 2 instances at one time. &nbsp; Unlike normal&nbsp;languages (C++, VB, Perl), I&nbsp;can not print my code to see what went wrong (viewing on&nbsp;a screen is more&nbsp;difficult than looking at it on paper), and I can not use conventional comparison tools.

&quot;self reference&quot; vi labview 7
I'm searching in Labview 7.1 for a "this vi" reference node but can't find it. I know that it is possible to create one, i once did it. In higher versions of Labview it is available from the palettes. Do you know a solution for Labview 7.1? Hi vlipje, you don�t need it. You can right click on the property node and select "Select class -&gt; VI Server -&gt; VI -&gt; VI". This should also work. Mike To get the reference to the current VI: File I/O &gt;&gt; File Constants &gt;&gt; Current VI Path wired to Application Control &gt;&gt; Open VI Reference. This reference can be passed to a subVI over a VI Refnum control. For working with the same VI the method of MikeS81 is prefered. Thanks Mike, this is a nice and clean solution, even better than what i had in mind.. Indeed MikeS81 solution was what i was searching for. This one is also an nice solution, thanks ...

But for the below function LabVIEW is crashing. &nbsp; void SFCCU_GET_IMG_RAW_DATA(unsigned long *length,unsigned char** pImgData,unsigned int iCamObj) According to the doccumentation of the dll provided, pImgData is 1D array. I tried the same dll in VC++. I can able to acheive the result of he above function properly. I attached the Call Library Function Node.vi's prototype with this mail what i have done.
