Lines that would be executed even if an error occur or if the script is aborted

When running a script and an error occurs, everything stop. The lines following the line where the error occurred wont be executed. Same think if I do ctrl-c to abort the execution.

I am using fopen and a visa object. I always have to run those line at the end of the script to close the communication to be able to reopen it when rerunning the script:

fclose(vu);

delete(vu)

clear vu

Is there a way to get these lines executed even if an error occurs before these lines or if I use ctrl-c before the script gets to these lines.Like an emergency part of the code that have always to be executed at the end no matter what.

What I am doing now is write those line manually those line in the command window when my script fails.

Thanks

Hi Camil,

You can use try..catch. For example

try
  foo()
catch
  fclose(vu);
  delete(vu);
  clear vu;
  error(...);
end

try/catch cannot handle control-C

Thank you very much. It works very well.

No, there is no way to do what you want with a script. With newer versions of MATLAB, however, it can be done inside a function, using oncleanup().
