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: performAMICA.m
    path of file: ./repos/automagic/preprocessing
    
    the code of the file until where you have to start completion: function EEGClean = performAMICA(EEG, varargin)

%% NEED TO EDIT THIS
% performAMICA  perform adaptive ICA using multiple models with shared components (AMICA) 
%   This function applies a high pass filter before the ICA. But the output
%   result is NOT high passed filtered, rather only cleaned with ICA. This
%   option allows to choose a separate high pass filter only for ICA from
%   the desired high pass filtered after the entire preprocessing. Please
%   note that at this stage of the preprocessing, another high pass filter
%   has been already applied on the data in the performFilter.m. Please use
%   accordingly.
%
%   data_out = performMARA(data, params) where data is the input EEGLAB data

%
%   data_out = performMARA(data, params) where data is the input EEGLAB data
%   structure and data_out is the output EEGLAB data structure after ICA. 
%   params is an optional parameter which must be a structure with optional 
%   fields 'chanlocMap' and 'high'. An example of params is given below:
%
%   params = = struct('chanlocMap', containers.Map, ...
%                     'largeMap',   0, ...
%                     'high',       struct('freq', 1.0, 'order', []))
%   
%   params.chanlocMap must be a map (of type containers.Map) which maps all
%   "possible" current channel labels to the standard channel labels given 
%   by FPz, F3, Fz, F4, Cz, Oz, ... as required by processMARA. Please note
%   that if the channel labels are already the same as the mentionned 
%   standard, an empty map would be enough. However if the map is empty and
%   none of the labels has the same semantic as required, no ICA will be
%   applied. For more information please see processMARA. An example of
%   such a map is given in systemDepend
