You have to get the 'String' value of the listbox, which will be a cell array.
currentItems = get(hListbox, 'String');
Set the row for the item you want to remove equal to[].
newItems = currentItems;
newItems(rowToDelete) = []; % Or something like that - maybe it's {}
Then send the cell array back to the listbox with the
set(hListbox, 'String', newItems)
function.

Note:
if get(hListbox,'ListboxTop') >= min(rowToDelete)
then you will want to set(hListbox, 'ListboxTop') to a different value as otherwise it will point to the wrong place or point past the end of the new list.

You're going to have to use something like sscanf() to parse the number out of the line of text. Basically strip off the numbers and rebuild your list from scratch with new numbers.
