I have tried to use the:

if ~isdeployed
  addpath('pathname')
end

But this isn't working still once it's been compiled. I am working on a Linux machine if this helps.

If anyone can help it would be much appreciated.

Thanks

Can you deploy scripts? I thought it is only functions you can deploy.

When something is compiled, isdeployed becomes true, and since you test ~ of that, the addpath() would not be called.

Compiled executables cannot change their path at runtime. You need to add the paths to the lists of places to look at compile time, or you need to use the -a option if you are using mcc, or you need to add the path before you compile; see https://www.mathworks.com/matlabcentral/answers/314624-how-to-use-addpath-in-compiled-matlab-code

If you are trying to use addpath to choose between different routines with the same name at run-time, then Don't Do That (TM).
