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: VBA_spm_eeg_render.m
    path of file: ./repos/VBA-toolbox/thrid-party/spm
    
    the code of the file until where you have to start completion: function  [out] = VBA_spm_eeg_render(m,options)
% Visualisation routine for the cortical surface
% FORMAT [out] = spm_eeg_render(m,options)

% INPUT:
    
function doSwitch2nextCluster(btn,evd)
v00=get(btn,'value')+1;
udd00=get(gcbo,'userdata');
ind00=min([v00 udd00.nc+1]);
set(udd00.pop,'value',ind00);
set(udd00.p,'facevertexcdata',udd00.tex(:,ind00));
if ind00 == 1
    colormap(udd00.col);
else
    col00 = colormap(jet);
    col00(1:end
