MATLAB: Potential error when compiling a folder path inside a GUI

compilerfolderguipath

Recently i have programmed a functional GUI, but in order to work it needs to change directory and use the information from an specified path folder. Now i need to turn this into an executable using the Compiler. I fear the code will not work since the path directs to a folder within the PC and the executable must run in other computers. Is there a way to include this foreign folder when compiling the GUI?

Best Answer

it has two ways:

1. either compile the .exe with the data in the folder 2. or ask the path input during compilation

Best practice is to use fullfile() with ctfroot to construct the filename, and winopen() that

filename = fullfile(ctfroot(), 'TrainedData\Romulus\physcons.xlsx');
winopen(filename);

You're best off not referring to files without the full path prepended. The folder where you put the executable is not the "real" folder where the "real" executable is located. What the first one does is to unpack the real executable and all the other stuff you included with it into some secret hidden folder. What I do is to ship data files and install them to some known location - a known folder - and then have my code point to it there. There are ways to get the actual folder it's running from if you need it.
