MATLAB: How to remove file extension when using ugetfile in app designer

app designerfileMATLABmatlab guixlsread

Hi All

I use

[filename,pathname] = uigetfile('*.xlsx');% add ur extension post period within parathesis.
fullfilename = fullfile(pathname,filename);
A = xlsread(fullfilename); % if it is a excel file. else use whatever it is.

but then I need to use the filename but without its extension, how do I do that in app designer

The easiest way to remove an extension is with fileparts:

[p,f,e]=fileparts(fullfilename);
fullfilename=fullfile(p,f);

'test.xls' is not in your current folder. Perhaps it's really called 'test.xlsx' or perhaps it's in a different folder. You can specify the folder it lives in and then use fullfile() to create the full file name.

folder = 'c:/whatever'
fullFileName = fullfile(folder, 'test.xls');
a = xlsread(fullFilename);

OR use the following to have the user manually locate it:

% Have user browse for a file, from a specified "starting folder."
% For convenience in browsing, set a starting folder from which to browse.
startingFolder = 'C:\Program Files\MATLAB';
if ~exist(startingFolder, 'dir')
  % If that folder doesn't exist, just start in the current folder.
  startingFolder = pwd;
end
% Get the name of the file that the user wants to use.
defaultFileName = fullfile(startingFolder, '*.xl*');
[baseFileName, folder] = uigetfile(defaultFileName, 'Select a file');
if baseFileName == 0
  % User clicked the Cancel button.
  return;
end
fullFileName = fullfile(folder, baseFileName)
a = xlsread(fullFilename);
