The tf and related functions can take name-value pairs to define such as 'TimeUnit'. From the tf documentation:
  • Any of the previous syntaxes can be followed by property name/property value pairs
  • 'Property',Value
  • Each pair specifies a particular property of the model, for example, the input names or the transfer function variable. For information about the properties of tf objects, see Properties. Note that
  • sys = tf(num,den,'Property1',Value1,...,'PropertyN',ValueN)
  • is a shortcut for
  • sys = tf(num,den)
  • set(sys,'Property1',Value1,...,'PropertyN',ValueN)
See the Properties section (a bit more than half way down the page) for details.
