Math Interface toolkit and LabVIEW 7.1 versus 7.0

[paris1_]

I recently purchased the LabVIEW Math Interface Toolkit (for Matlab) and what I received was version 1.0 of the Toolkit. I installed it into my version 7.1 (note that it is 7.1 and not 7.1.1) of LabVIEW and discovered it would not work. I wasn't sure if it was me or a software issue so I began searching. I found a KnowledgeBase article that said in order to get this toolkit to work with LabVIEW 7.1 I had to first use the Add/Remove Programs feature of Windows to Repair LabVIEW.. That seemed a bit strange but I tried it... I did the repair that went on for quite a while but when I again tried to run the Math Interface Toolkit, still no positive results... Then I saw a post somewhere that said this version would only work with version 7.0 of LabVIEW which I also have installed on my machine... So I uninstalled the Interface toolkit from 7.1 and reinstalled it into the version 7.0 folder... I then tried to build and run a .dll file from within LabVIEW 7.0 and it worked like a champ... Does anyone know if National has or is going to upgrade the Math Toolkit so it will run under 7.1??? I saw a listing somewhere that mentioned a version 1.0.1 of the Toolkit but I can find such nowhere... And a second question would be (now that I have discovered how to make it work), if I want to run .dll on a target machine that will have Matlab but not LabVIEW installed, what do I need to put on that target machine (related to this toolkit)... I think I need what's called the NI Math Interface Run-Time 1.0. I see that on my machine (in Add/Remove programs under National Instruments) but I don't see a way to install that as a stand alone piece of code. It would seem that I might have to install the entire Math Interface Toolkit on the target machine even though I would not be using that machine to build the .dll's, instead only to run them... Oh, and does anyone think that perhaps this toolkit would work under 7.1 if I upgraded to 7.1.1??? Any thoughts?? Any input would be appreciated... thanks... bob...

Hi Bob,

I just tested this behavior on my machine and was able to successfully create and use the dll and m files in Matlab. I have LabVIEW 7.1 installed with MIT 1.0. I think your problems must be due to a bad-installation. I would recommend uninstalling and reinstalling LabVIEW 7.1 and MIT 1.0 on your machine. If that still doesn't work, I would try uninstalling LabVIEW 7.0 & 7.1 and then just reinstalling LabVIEW 7.1 and MIT 1.0. If that doesn't work, I will be amazed. If that still doesn't work, try installing LabVIEW 7.1 and MIT 1.0 onto a clean machine just to verify that you are able to do so.

And yes, to use the created dll and m files in Matlab, you will need to have these three things installed on the distribution computer:

1) LV RTE for the version of LabVIEW that was used to create the files.
2) MIT RTE
3) Matlab, obviously

Hope this helps,
