How to use addpath in compiled matlab code

I am trying to create an executable out of a simple matlab code. It uses "addpath" to refer to files in a different directory. During execution This yields an error of this and the message below.

This is typically caused by calls to ADDPATH in your startup.m or matlabrc.m files. Please see the compiler documentation and use the ISDEPLOYED function to ensure ADDPATH commands are not executed by deployed applications.

If I enclose the addpath with an ~isdeployed guard, then the routine is not found at runtime. Can you tell me what I do wrong?

Thanks and best regards,

Gabriele

This is how I use the isdeployed:

if ~isdeployed
addpath <mypath>/test/ECCO2PlotCode
end
nx=4320;                    % llc face dimension
kx=90;                      % number of vertical levels

'step2' % plot test U
j1=1
j2=1
for jj=(j1+50):(j2+50)
for i=0:1:24
jj, i
ts=10368+144*24*(jj-1)+i*144;

myint2str(ts,10)

end %for i=0:1:24
clear U V;
end %for jj=1:392

I see no reason why that code would even need addpath(). If it's just because you need to run myint2str(), don't worry about it. The compiler will find it for you.

If you want to load and save files to a particular folder, then just construct the full filename and use that rather than saving and loading from the current directory or to/from some folder on the search path.

Thanks so much for the feedback. In the small example it is just for using myint2str. The real application is more complicated. To run it interactively, the addpath is needed. Can you advise me how to change the code so that the compiler will find the routine? Thanks in advance, Gabriele

The addpath is not needed. Do the addpath first before you compile.

If you have path conflicts, the same routine in multiple locations, distinguished by manipulating the path, then that would be a problem.

Well now you have two of us saying it's not needed. If you still insist, possibly to enable bad programming practices later in your program, then you can put addpath in yourstartup.m file like the error message said.

Using the GUI and doing the addpath before compilation helped for my small test case. Many thanks for the help and useful information.
