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: CreateAgeMatrixFromParams.m
    path of file: ./repos/VFIToolkit-matlab/SubCodes/ParameterStructure
    
    the code of the file until where you have to start completion: function AgeMatrixOfParamValues=CreateAgeMatrixFromParams(Parameters,ParamNames,N_j) %,index1,index2)
%

    
function AgeMatrixOfParamValues=CreateAgeMatrixFromParams(Parameters,ParamNames,N_j) %,index1,index2)
%
% AgeMatrixOfParamValues=CreateAgeMatrixFromParams(Parameters,ParamNames,N_j)
% AgeMatrixOfParamValues=CreateAgeMatrixFromParams(Parameters,ParamNames,N_j,index1)
% AgeMatrixOfParamValues=CreateAgeMatrixFromParams(Parameters,ParamNames,N_j,index1,index2)
%
% CreateAgeMatrixFromParams looks in structure called 'Parameters' and 
% then creates a matrix with each column contains the values of it's fields that
% correspond to those field names in ParamNames (and in the order
% given by CalibParamNames) and each row is a different age (j).
%
% Some parameters are stored in the Parameters structure as vectors or
% matrices (eg., because the parameter values depend
