You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: randoms_smoothing.m
    path of file: ./repos/OMEGA/source
    
    the code of the file until where you have to start completion: function randoms = randoms_smoothing(randoms,options)

    
function randoms = randoms_smoothing(randoms,options)
%RANDOMS_SMOOTHING Performs a moving mean smoothing on randoms or scatter
%data
%   Input randoms/scatter sinogram/raw list-mode data is smoothed by using
%   a 7x7 moving mean smoothing. The parameters Ndx and Ndy can be used to
%   adjust the size of the mean window. Smoothing is done symmetrically by
%   taking the mirror images of the measurement data on all sides. Outputs
%   the smoothed sinogram/raw list-mode data.

    disp('Beginning randoms/scatter smoothing')
