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: StateSpaceSubdivisionGaussianDistribution.m
    path of file: ./repos/libDirectional/lib/distributions/LinearBoundedCartProd
    
    the code of the file until where you have to start completion: classdef StateSpaceSubdivisionGaussianDistribution < StateSpaceSubdivisionDistribution
	
    methods
        function this = StateSpaceSubdivisionGaussianDistribution(gd_, gaussians)
            arg
    
function C = linearCovariance(this)
            % Computes covariance of linear dimensions
            %
            % Returns:
            %   C (linD x linD)
            %       covariance matrix
            %
            % Reinterpret as GM to get linear covariance.
            arguments
                this (1,1) StateSpaceSubdivisionGaussianDistribution
            end
