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: translate.m
    path of file: ./repos/spinw/swfiles/+swplot
    
    the code of the file until where you have to start completion: function translate(mode, hFigure)
% translates objects on swplot figure
% 
% ### Syntax
% 
% `swplot.translate(mode)`
% 
% `swplot.translate(mode, hFigure)`
%
% ### Description
% 
% `swplot.translate(mode)` translates the objects of an active swplot
% figure, where the coordinate system is defined by the plane of the figure
% with horizontal $x$-axis, vertical $y$-axis and out-of-plane $z$-axis.
% 
% `swplot.translate(mode, hFigure)` acts on the figure referenced by the
% `hFigure` handle.
%
% ### Input Arguments
% 
% `mode`
% : Either a vector with three numbers that determine the translation 
%   vector in the figure plane coordinate system, or `'auto'` that
%   centers figure to the middle of the objects. Default value is `'auto'`.
% 
% `hFigure`
% : Handle of the swplot figure, default value is the active figure.
%
