MATLAB: A question about function — uigetfile()

uigetfile

the code

 [FileName PathName]=uigetfile(('*.xlsx'), 'Choose a File');

runs Ok; but the code

 [FileName PathName]=uigetfile(('*.xlsx','Excel Files(*.xlsx)'; '*.txt','Txt Files(*.txt)'), 'Choose a File');

runs wrongly. why? how should I modify it?

Hi.. Try this code:

[filename, pathname] = uigetfile({'*.xlsx','Excel Files(*.xlsx)'; '*.txt','Txt Files(*.txt)'}, 'Pick a file');

I think it's only missing the {};

MATLAB: Fullfile to contain multiply file extension

Try:

filePatternCSV = fullfile(handles.sourceFolder, '*.csv'); 
csvFiles = dir(filePatternCSV); 
filePatternXLS = fullfile(handles.sourceFolder, '*.xls'); 
xlsFiles = dir(filePatternXLS);
filePatternODS = fullfile(handles.sourceFolder, '*.ods'); 
odsFiles = dir(filePatternODS);
allFiles= vertcat(csvFiles,xlsFiles,odsFiles);

MATLAB: Pre-initialize output variable based on uigetfile() result.

Use a temporary variable.

function outFile = fcn()
  coder.extrinsic('uigetfile');
  [uiselectedFile, pathname, fileindex] = uigetfile('*.dat','Select the DAT input file');
  L =length(uiselectedFile)
  temp = zeros(1, L, 'uint8');   %more efficient than uint8() of zeros()
  outFile = temp;

It is not clear to me why you are not emitting the chosen name itself? You do not want to have to prompt the user for it again.

It is also not clear to me why you are not outputting the path.

Also remember that uigetfile() will return numeric 0 if the user cancelled.

And finally... what if the user selects a name that includes characters beyond code position 255?
