I have to load data from a .m file to a uitable, thats my code:
diretorio = uigetdir;
filename = uigetfile('*.mat','Select the MATLAB code file');
d = ' \';
e = strtrim(d); % Usado para salvar "/" em forma de string
Dados_1 = strcat(diretorio,e,filename);
Dados_2 = open(Dados_1);
As you can see, its not functional, once i need to ask for the directory name, the file name, then manipulate strings and finally open it. Is there a function that opens files from different directorys?

Accept BOTH return values from uigetdir(), then combine them with fullfile().

It was very usefull, but i want to know if is there a function that get the directory name when i select the file, or something like that, because its not functional ask the name of both directory and file name, once this code will be used to interact with the user, tks!

I think you mean the two return arguments of uigetfile().

I don't know why you say that. It's almost like you didn't even look at the help for uigetdir and fullfile. If you had, you would have seen that it's a simple process to do get both return values/arguments and combine them like this:
[baseFileName, folder] = uigetfile('*.*', 'Specify a file');
fullFileName = fullfile(folder, baseFileName);

Sorry, I didnt understood well when I readed at the first time, I just got that fullfile will help me to put the names together, but didnt realized about the uigetfile. In fact I even dont need the fullfile anymore because I can use the function load to open:
[filename, caminho] = uigetfile('*.mat','Select the MATLAB code file');
Data_1 = load([caminho filename]);

I recommend to use "load(fullfile(caminho filename));" instead. In opposite to the simple concatenation it cares for the necessary file separators.
