function [P, U] = approximate_points(Q, p, alpha, TOL)
    % INPUT
    % Q - data points, [dim, n_points]
    % p - degree of spline
    % alpha - parametrization strategy, 1.0-chord-lengt, 0.5-centripetal
    % TOL - tolerance of curve approximation
    %
    % OUTPUT
    % P - control points of spline curve
    % U - knot-vector of spline curve
    
    if ~ismatrix(Q)
        fprintf('the Input Q must be matrix \n');
        return
    end

    [P, U] = approximate_points_impl(Q, p, alpha, TOL);
end
