using '!' in matlab script

[eternityzh]

It seems unable to invoke the '.EXE' file in the matlab script node.

In my matlab code I use '!' to invoke a .exe file, it can be execute in matlab, but when I copy the same code to labview(matlab script node), it does not work

the error messages are

LabVIEW:  Error occurred while executing script. Error message from server: Warning: Name is nonexistent or not a directory: D:\Wastewater_experiment\programCodes\DymolaFiles.
> In c:\matlab6p5\toolbox\matlab\general\path.m at line 116

... Error message from alist

??? Error using ==> load

On line 17  ==> [x_init, x_name] = initload; % loads initial conditions from txt-file 'dsin.txt'.

. in labviewmatlab.vi

I am sure I have add all the path. and If I just run the code

! alist -a dsin.txt dsintest.mat

in matlab script node. There is no errors but it can not be execute.

This alist.exe file is from 'Dymola' to transfer the 'txt' to 'mat'.

How can I do with this error

Hi eternityzh,

Could you please post the code that is causing the error code (I have not been able to reproduce the error with the files that was posted). Thanks!

Best regards,

Sorry
The problem have solved.
When I invoke .txt .mat .exe in LabVIEW matlab script node, this files should be under '.../matlab' path. I do not kown why it is not '.../matlab/work'.And 'addpath' is useless except to 'invoke .m' files.
It can work now.
