matlab runtime string error

[yuval_yohai]

Hello,

I'm running labview with a matlab script that runs OK .

after compiling I get

"parameter must be a string" error

my runtime engine is 7.1.1

any ideas

Where does the script run OK. In Matlab, or in LabVIEW? When does the error come up? When you build the application, or when you run the application? Please provide more details. Seeing the code would help also.

The script runs OK at labview.

the error comes up when I ran the compiled labview application right after the matlab block is done at the "error out" output.

The code is not on this computer.

The matlab code though is very simple:

" 

cd(vriablename);

 someMatlabFunction;

"

the CD function is unable to operate since my input is not a string (so does the error say)

thanks,

Yuval

I have just found that this happens only on runtime 7.1.1

with 7.1 it works OK

What version of Matlab do you have installed on the machine that's running the LabVIEW app?

[yuval_yohai]

matlab 6.5.0.1.180913a release 13

Hi Yuval,

You said that the built application runs with the 7.1 runtime engine but not with the 7.1.1 runtime engine.  What version of LabVIEW was the applications built in?  You have to use the runtime engine from the version of LabVIEW it was built in. 

Also,  does the machine that you are trying to run the application on have the same version of MATLAB® as the development machine?
