Returns the root mean square value of the supplied vector offset by its mean between the ranges specified by arguments 2 and 3. If the values supplied for argument 2 and/or 3 do not lie on sample points, second order interpolation will be used to estimate y values at those points.
Offsetting the input data by its mean effectively AC couples the data so that any DC component in the data is removed.
