I am running a concurrent License. Toolboxes are installed according to 'ver' command. The scripts I am trying run are in the path, however, whenever I run a scrip the message ' undifined function or variable 'xxxxx'.' comes up. Commands work line by line but as soon as a Matlab function (or another script) are called I stop beeing able to run them.

Not sure what is going on. Could this be a license issue? Doesn't seem so as commands are working....

Any help would be great! Thanks.

your scripts might be changing directory
your scripts might be altering the path
your script name (or the directory you are in) might just happen to match the name of one of the MATLAB directories used for toolboxes; in such a case MATLAB might get confused and think they are part of MATLAB and that you need a license for the toolbox it believes they are

What does which -all of the name show when it fails?
