	function filtered = gaussianFilter(img, sigma, varargin)
	% GAUSSIANFILTER Simplified open-source version of IMGAUSSFILT
	% The IMGAUSSFILT function is part of the Image Processing Toolbox,
	% but if you don't want to install that, then use this
	% instead. I haven't actually tested this to ensure it gives the same result.
	% Inspired by https://stackoverflow.com/questions/13193248/how-to-make-a-gaussian-filter-in-matlab
	%
	% Hardcodes in the default arguments of IMGAUSSFILT
