gsubtract Error

Hello,
Fairly new to MATLAB and having some issues with a code I'm working with. I'm attempting to produce a multivariate local linear regression M file which makes use of gsubtract to find deviations from an expected value. When I run the code, which looks like this: a = (1/h(j))*gsubtract(reg(:,j),reg(:,j)');" I get the error "??? Undefined function or method 'gsubtract' for input arguments of type 'double'." I have looked everywhere for a solution to this problem, but can't seem to find why I would be having trouble with this command. h(j) is simply a vector (the command is inside a loop), and reg is just a matrix. Do I just have the wrong version of Matlab (I have R2009b) or do I have to call something special before I can use the command?
Any help would be greatly appreciated.

gsubtract is part of the Neural Network Toolbox. If you do not have the NN Toolbox installed and licensed, you would get that error.

R2011 only have gsubtract.m, older versions of Matlab don't have this file :(
