Can I control a labview executable with matlab?

15 views (last 30 days)
I'm aware this is a bit of a long shot, but it wouldn't be the first time matlab's capabilities have surprised me.
For a project, I have to make rovibrational fits to a nitrogen optical emission spectrum. The problem is that I have several thousand spectra and more to come. It would take me weeks to process them manually and so I want to automate this using Matlab. I got a program that can do these fits, but it is a labview .exe file and I have not received the source code. I was wondering if it is still possible to connect the two.
What I would like to do:
- Have Matlab give LabView a file
- Tell LabView to make a fit (the program has a designated button for this, if that helps)
- Save or extract the fitted parameters (it has a button for this as well)
- Save or extract the fitted curve (also a button)
e=actxserver('LabVIEW.Application');
vipath='C:\Users\...\fit_spectra_N2_SPS_main.exe';
vi=invoke(e,'GetVIReference',vipath);
Obviously this wants a vi, so I tried finding what sort of method the ‘.exe’ file would be, but couldn’t find that. If I try it like this, I get the error:
Error using COM.LabVIEW_Application/GetVIReference
Invoke Error, Dispatch Exception:
Source: LabVIEW
Description: LabVIEW: (Hex 0x423) Unexpected file type.
I've also tried a suggestion on the National Instruments website (https://forums.ni.com/t5/LabVIEW/MATLAB-calling-subVi/td-p/906758) But that seems to only change the way the invoke function is called. Either way, it gives me the exact same error.
After a lot of googling and coming up empty-handed, the last thing I tried was ask a friend who - though he's not very familiar with matlab - has a lot of programming experience. He expected it to be impossible, but recommended I ask here regardless.
So is it possible to control a labview executable (which I do not have the source code for) with matlab?
If it does happen to be possible, can you point me in the right direction to get started? Because I honestly have no idea how to go about it anymore.

MATLAB and LABVIEW are two very distinctly different programs. If you wanted to pass inputs/outputs, you could do that. But having MATLAB call a labview program is impossible.
