LeadLag:

Path: Common/Control

% Create a lead or lag.
   
   Create a lead or lag with the appropriate phase characteristics
   in the form  

              tau1 s + 1
   K(s) = Kdc ----------
              tau2 s + 1

   Given the desired maximum phase magnitude (90) and frequency

--------------------------------------------------------------------------
   Form:
   [a, b, c, d] = LeadLag( wmax, phasemax, Kdc, tSamp, sType )
--------------------------------------------------------------------------

   ------
   Inputs
