I have a GUI using a Browe Button to search a file :
function Browse(app, event)
FileName,FilePath ]= uigetfile();
ExPath = fullfile(FilePath, FileName);
app.FileTextArea.Value = ExPath;
end
And i save the file Path in a Text Area. I have another button that start a matlab script with the file path as parameter and so i would like to accept only a certain type of file (.ctm which is my own type of file) if possible like this :
if file is .ctm
do something
else
print('a .ctm file is needed')
Thanks for helping

doc uigetfile
gives examples of specifying filters for file type.
You can use a generic uigetfile and a check like that after if you prefer, but it seems to make more sense to just use the uigetfile filter, e.g.
[file, path] = uigetfile( '*.ctm', 'Some title or other' )
though there are fancier options too.
