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: achse.m
    path of file: ./repos/hctsa/Toolboxes/OpenTSTOOL/tstoolbox/@achse
    
    the code of the file until where you have to start completion:  function a = achse(argument, varargin)

%tstoolbox/@achse/achse
%   achse class constructor
%
%   Syntax:
%     * a = achse
%       creates default achse object
%     * a = achse(axs)
%       copies achse object axs into a
%     * a = achse(unt)
    
function a = achse(argument, varargin)

%tstoolbox/@achse/achse
%   achse class constructor
%
%   Syntax:
%     * a = achse
%       creates default achse object
%     * a = achse(axs)
%       copies achse object axs into a
%     * a = achse(unt)
%       creates achse object using unit unt, with linear spacing, first =
%       0, delta = 1
%     * a = achse(vec)
%       creates achse object with arbitrary spacing, using values in vec
%       as spacing data
%     * a = achse(unt, vec)
%       creates achse object using unit unt with arbitrary spacing, using
%       values in vec as spacing data
%     * a = achse(unt, first, delta)
%       creates achse object with linear spacing, using delta and first
%     * a = achse(unt, first, delta, 'log')
%       creates achse object with logarithmic spacing, using delta and
%       first
%
%   achse used to describe the different dimensions (axes) of a signal
%   object.
%
%   Example:
%     * a = achse(unit('Hz'), 0.01, 10, 'log')
%       creates a logarithmic frequency axis with values 0.01 Hz, 0.1 Hz,
%       1 Hz, 10 Hz
%     * a = achse(label, samplerate)
%       has the same result as
%       a = achse(unit(label), 0, 1/samplerate)
%
