Is there an error in the example script in the "Constructing SISO models" entry in the documentation for Control System Toolbox 6.1 (R14SP1)?

In the DC Motor example under Help -> Control System Toolbox -> Getting Started -> Building Models -> Linear Models -> Constructing SISO Models, the units for the inertia J are listed as kg.m^2/s^2. I think they should be kg.m^2.

This bug has been fixed in Release 14 Service Pack 2 (R14SP2). For previous releases, please read below for any possible workarounds:

This has been verified as an error within the documentation for Control System Toolbox 6.1 (R14SP1) within the Constructing SISO Models section. The documentation should read as follows:

 R= 2.0 % Ohms

 L= 0.5 % Henrys

 Km = .015 % torque constant

 Kb = .015 % emf constant

 Kf = 0.2 % Nms

 J= 0.02 % kg.m^2
