Uploading multiple .txt files at once on MATLAB GUI

I would like some guidance on how to import multiple .txt files containing data seperated by comma on a MATLAB GUI. Once the files are uploaded, I have a function that will manipulate all the data from each .txt file.

Any help is appreciated.

Try uigetfile to launch a dialog for loading files. Set 'MultiSelect' to 'on' in order to select multiple files at once.

Here's an example call:

[filenames, pathname] = uigetfile({'*.txt; *.csv','Comma separated values';...
           '*.*','All files'},'Select files','MultiSelect','on');

You will need to check if the user actually selected a file or if they canceled.

If I understand your question correctly, you have a GUI already. In this case you just need to add the above call to your designated callback function (i.e. whatever you click to invoke this file load interface).

The easiest way to import multiple files is to:

  • Use the file importer GUI in matlab and generate a script after you
    selected your preferred parameters
  • Generate a script (there is a button to generate a script in the importer)
  • Modify the script with a for loop to load multiple files and save them in a variable (a cell array can handle different sizes of data in each file)
