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: ica_fuse_runica_ccica.m
    path of file: ./repos/fit/FITv2.0e/ica_fuse/ica_fuse_analysis/ica_fuse_ica_algorithms
    
    the code of the file until where you have to start completion: % runica() - Perform Independent Component Analysis (ICA) decomposition
%            of psychophysiological data using the infomax ICA algorithm of
%            Bell & Sejnowski (1995) with the natural gradient 
    
function [weights,sphere,activations,bias,signs,lrates,testrecord, y] = ica_fuse_runica_ccica(data, p1,v1,p2,v2,p3,v3,p4,v4,p5,v5,p6,v6,p7,v7,p8,v8,p9,v9,p10,v10,p11,v11,p12,v12,p13,v13,p14,v14,p15,v15,p16,v16)
%% make sure the most important vector used first, benefit for the initialization
% data=flipud(data);
