MATLAB: “Value must be a handle” error during Patch

errorhandleMATLABpatch

Hi!
I'm a Matlab beginner. I was trying to plot a parallelepiped with the patch command. This is the list of my faces:
ff =
       1     2     4     3     1
       1     2     6     5     1
       5     6     8     7     5
       3     4     8     7     3
       2     4     8     6     2
       1     3     7     5     1
and this is the list of my nodes:
nodes =
     0     0     0
     0     0    20
     0    10     0
     0    10    20
    15     0     0
    15     0    20
    15    10     0
    15    10    20
then I use this code to plot the geometry:
patch('Face',ff,'vertices',nodes2)
but I only get this error:
Error using patch
While setting the 'Face' property of 'Patch':
Value must be a handle.
I get this message even if i try to plot single faces indipendently. Where am I failing?

ff =   [1     2     4     3     1
       1     2     6     5     1
       5     6     8     7     5
       3     4     8     7     3
       2     4     8     6     2
       1     3     7     5     1] ;
     nodes = [ 0     0     0
       0     0    20
       0    10     0
       0    10    20
      15     0     0
      15     0    20
      15    10     0
      15    10    20] ;
patch('Faces',ff,'vertices',nodes)
