Open folder selection dialog box

selpath = uigetdir opens a modal dialog box that displays the folders in the current working directory and returns the path that the user selects from the dialog box.

This dialog box enables a user to navigate to a folder and select it (or type the name of a folder). If the specified folder exists, then MATLAB® returns the selected path as a character vector when the user clicks OK. If the user clicks Cancel or the close button (X) on the title bar, then MATLAB returns 0.
