This is the code I'm currently working on, but when I run menu #4, I get an error saying the index exceeds matrix dimensions.

close all;
clear all;
clc;
n=2;
filename='data';
A={'Vehicle model number','Vehicle purpose','Vehicle registration number','starting year of registration','ending year of registration', 'owner'};
count=0;
while(1)
    
    fprintf(''     *programme name*     \n')
    fprintf('---------------------------\n')
    fprintf('1) vehicle registration\n')
    fprintf('4) vehicle registration statistics\n')
    fprintf('0) close the programme\n')
    fprintf('---------------------------\n')
    m=input('Enter the choice : ');
    if m==1
        fprintf('     *1) vehicle registation     \n')
        fprintf('---------------------------\n')
        number=input('- Vehicle information number       :','s');
        year=input('- starting year of registration(year) :');
        period=input('- registration period(year)    :');
        owner=input('- owner          :','s');
        Anew={number(1:3),number(4),number(5:8),year,year+period,owner};
        A(n,1)=(Anew(1,1));
        A(n,2)=(Anew(1,2));
        A(n,3)=(Anew(1,3));
        A(n,4)=(Anew(1,4));
        A(n,5)=(Anew(1,5));
        A(n,6)=(Anew(1,6));
        n=n+1;
    end
    
    if m==4
        fprintf('     *4) vehicle registration statistics     \n')
        fprintf('---------------------------\n')
        fprintf('Statistical conditions \n')
        fprintf('1) registration period \n')
        fprintf('2) purpose of registered vehicle \n')
        fprintf('---------------------------\n')
        choice=input('');
        if choice==1
            fprintf('---------------------------\n')
            result=input('enter the registration period:');
            fprintf('---------------------------\n')
            for i=2:n
                period_1=cell2mat(A(i,5));
                period_2=cell2mat(A(i,4));
                period_search=(period_1-period_2);
                if result==period_search
                    count=count+1;
                end
            end
            fprintf('---------------------------\n')
            fprintf('There are %d vehicles \n', count)
            fprintf('---------------------------\n')
        end
        
       
    end
    if m==0
        xlswrite('data',A);
        break; 
    end
    end
