MATLAB: How to save the data of an opened file by uigetfile in the workspace

Question

hello all,

i want to create a window that would be opened by a pushbutton, to open a file (a txt file) and then to load it to the workspace of matlab, i tried this code, it worked correctly but in the end i found nothing in the workspace, it doesn't save the data

filename = uigetfile('*.txt*',  'All Files (*.txt*)');
filename = uiimport(filename);

thank you.

imene - rather than re-using the same variable name for the data that is being imported, try

 filename = uigetfile('*.txt*',  'All Files (*.txt*)');
 data     = uiimport(filename);

Now data is a struct that has the data that you have imported..which is in the workspace of your pushbutton callback. Depending upon how you have developed your GUI, you can either save this data to the handles structure (if using GUIDE) or you can save it to a local variable within your parent function that creates the GUI (assuming that you have nested your callback within that parent).
