crash due to matlab function

[jwan887]

Hi All,

My LabVIEW VI crash (Exception: Access violation (0xC0000005) at EIP=0x00000000) when it runs to a matlab function "inv". Seems it is a normal matrix function and should be supported in mathscript. After I delete this function, everything works fine. Can someone give me any clue on how to fix this? The crash report is as following.

Thanks,

Jiaqi

PS: The LabVIEW I'm using is 2013 SP1 and the MATLAB is R2013b.

Are you using the Mathscript Node or the MATLAB® Script Node? Also, what is the size of the Matrix you are dealing with? Are you dealing with 32-bit or 64-bit LabVIEW?

The error message says 32bit. Seems the VI is loaded over the network.

Is your matlab 32 or 64bit?

Hi Miles,

I use Mathscript Node and the Matrix size is 3*3. LabVIEW is 32-bit. The funny thing is it worked fine yesterday afternoon and crashes again today with nothing changed:(.

Hi Altenbach,

You are right! The VI is loaded over the shared drive. Would this be the reason?

Have you tried to simply restart the computer and try again? Do you run any unusual antivirus software?

I tried to restart the computer but it didn't work. The antivirus software was installed by the uni IT so should be OK.
