I'd like to have a button on matlab app designer that when pushed, enables the user to select more files.

I tried first with one single file with this code and everything works well:

[filename,path] = uigetfile('*.txt');

If then, I try to select more files with the following code:

[filename,path] = uigetfile('*.txt','Select the files','MultiSelect', 'on');

I get this error:

Index exceeds the number of array elements. Index must not exceed 0.

Error in matlab.ui.internal.dialog.FileChooser/updateFromDialog (line 215)

obj.PathName = filepaths{1};

Error in matlab.ui.internal.dialog.FileChooser/prepareDialog/localupdate (line 95)

updateFromDialog(obj,updateDataObject(obj));

Can anyone help me with this?

Thanks

I do not think that this is the problem here, but redefining the important Matlab function "path" by a variable is a bad idea. This can cause strange side effects during debugging.

Did you modify one of Matlab's toolbox functions? This is only possible if you work with admin privileges. Or did you insert a function in Matlab's path, which shadows builtin functions? This could happen if you add user defined folders on top of the path. Prefer to append your folders on the bottom.

You could use thus tool to identify sahdowing functions: https://www.mathworks.com/matlabcentral/fileexchange/27861-uniquefuncnames
