Details:

With new textscan.cc in dev:

>> textscan (['Empty' char(10)], 'Empty%f %f')
ans =
{
  [1,1] = [](0x1)
  [1,2] = [](0x1)
}


Expected is {NaN, NaN}.

Adding any digit goes some way in the right direction:

>> textscan (['Empty1' char(10)], 'Empty%f %f')
ans =
{
  [1,1] =  1
  [1,2] = NaN
}


Matlab r2016a prerelease gives:
+verbatim-
>> format compact
>> U = textscan (['Empty' char(10)], 'Empty%f %f')
U = 
    [NaN]    [NaN]
