I guess from googling you got your erfz.m from
	http://www.mathworks.com/matlabcentral/files/3574/erfz.m

That function begins with
	error(nargchk(1, 1, nargin));

and runs if you comment out that line.

This looks like a compatibility bug in error, which is fixed by the  
attached.  Jaroslav, please also apply this to the 3.2.x series.
