MATLAB: Help with loading data from a folder in GUI

browsedataguiguideinterfacematlab gui

Hi everyone! I need to load some files from a folder, but I don't know how to save the directory. I'm using a GUI interface, and by using a push button 'Browse' I want to save the directory of my folder, e.g. 'C:\Users\Desktop\Folder1', which contains my data. Then, when pressing another push button to load my data, I want to be directed to this folder to take them, without browsing every time. How can I do? thanks

Did you see the uigetdir() function? Save the directory string it returns in a global variable, then use it with fullfile() whenever you need to create a filename.

Suhas - uigetdir returns a directory only so you need to specify a file name too. Perhaps something like

folderToSaveFileTo = uigetdir ("F: \");
filename = "someName.mat";
save (fullfile(folderToSaveFileTo, filename), "d");

Something like this?

[filename pathname] = uiputfile('*.sin','Save file as');
save(fullfile(pathname,filename),'varname','-ascii')
% or exchange last line with one of the following:
% save(fullfile(pathname,filename),'varname','-ascii','-tabs')
% save(fullfile(pathname,filename),'varname','-ascii','-double')
% save(fullfile(pathname,filename),'varname','-ascii','-double','-tabs')
