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: SphericalGridFilter.m
    path of file: ./repos/libDirectional/lib/filters
    
    the code of the file until where you have to start completion: classdef SphericalGridFilter < AbstractHypersphericalFilter & HypersphericalGridFilter
    
    methods
        function this = SphericalGridFilter(noOfCoefficients, gridType)
 
    
function this = SphericalGridFilter(noOfCoefficients, gridType)
            % Constructor
            %
            % Parameters:
            %   noOfCoefficients (integer > 0)
            %       number of grid values to use
            %	gridType (char)
            %       grid type to use for the SphericalGridDistribution
            arguments
                noOfCoefficients {mustBeInteger,mustBePositive}
                gridType char = 'eq_point_set'
            end
