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: suplabel.m
    path of file: ./repos/mpsim/lib/plot
    
    the code of the file until where you have to start completion: function [ax,h]=suplabel(text,whichLabel,supAxes)
% PLaces text as a title, xlabel, or ylabel on a group of subplots.
% Returns a handle to the label and a handle to the axis.
%  [ax,h]=suplabel(text,whichLabel,supAxes)
% returns handles to both the axis and the label.
%  ax=suplabel(text,whichLabel,supAxes)
% returns a handle to the axis only.
%  suplabel(text) with one input argument assumes whichLabel='x'
%
% whichLabel is any of 'x', 'y', 'yy', or 't', specifying whether the 
% text is to be the xlable, ylabel, right side y-label, 
% or title respectively.
%
% supAxes is an optional argument specifying the Position of the 
%  "super" axes surrounding the subplots. 
%  supAxes defaults to [.08 .08 .84 .84]
%  specify supAxes if labels get chopped or overlay subplots
%
% EXAMPLE:
%  subplot(2,2,1);ylabel('ylabel1');title('title1')
%  subplot(2,2,2);ylabel('ylabel2');title('title2')
%  subplot(2,2,3);ylabel('ylabel3');xlabel('xlabel3')
%  subplot(2,2,4);ylabel('ylabel4');xlabel('xlabel4')
%  [ax1,h1]=suplabel('super X label');
%  [ax2,h2]=suplabel('super Y label','y');
%  [ax3,h2]=suplabel('super Y label (right)','yy');
%  [ax4,h3]=suplabel('super Title'  ,'t');

%at beginning. Requires adding tag to the invisible axes
