Is there an error in documentation of the SIGNLMS function in the Communications Toolbox 3.3 (R2006a)?

When I type the following commands at the MATLAB command prompt

stepsize = 0.5;

alg = lms(stepsize,'Sign LMS')

I receive the following error message

 ??? Parameter must be scalar.

 Error in ==> lms at 29

 alg = adaptalg.lms(stepSize, varargin{:});

I would like to use the SIGNLMS function and specify the algorithm type.

There is an error in the documentation of the SIGNLMS function in the Communications Toolbox.

The documentation should read

alg = signlms(stepsize,algtype)

instead of

alg = lms(stepsize,algtype)
