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: setInput.m
    path of file: ./repos/PsPM/src/ext/VBA
    
    the code of the file until where you have to start completion: function [ u, dim, options ] = setInput(options,dim,varargin )
% allow to specify labels to inputs (u)
% IN
%     options: a structure
%     varargin: should be organized as: my_n1_times_nTrial_maxtrix1, name1, my_nk_times_nTrial_maxtrixk, namek...
% OUT
%     u : a concatenate (n1+...+nk) * nTrial matrix

    
function [ u, dim, options ] = setInput(options,dim,varargin )
% allow to specify labels to inputs (u)
% IN
%     options: a structure
%     varargin: should be organized as: my_n1_times_nTrial_maxtrix1, name1, my_nk_times_nTrial_maxtrixk, namek...
% OUT
%     u : a concatenate (n1+...+nk) * nTrial matrix
%     options is filled with options.in[FG].inputLabel.(each name) fields indexing the lines of u

n = numel(varargin);
assert(mod(n,2)==0,'***Parameters should be: name1, ''matrix1'', name2, ''matrix2'',...');
[~, nTrial]=size(varargin{2});
for i=1:2:n
    if islogical(varargin{i+1})
        varargin{i+1} = +varargin{i+1};
    end
