How can i create a general Code .m for TSP nxn, if i just had this code for more cities than 5? for example 6 cities, 7 cities, ... , 10 cities

%B is the matrix i have in a doc.txt

%i want a general code for every number of cities a distances

%B=[0 15 20 25 30; 15 0 16 18 24; 20 16 0 22 26; 25 18 22 0 28; 30 24 26 28 0] ]

function Viajeronew()

B=dlmread("Doc.txt")

tour_length(1)=B(1,2)+B(2,3)+B(3,4)+B(4,5)+B(5,1)

tour1='1,2,3,4,5,1' 

tour_length(2)=B(1,2)+B(2,4)+B(4,3)+B(3,5)+B(5,1) 

tour2='1,2,4,3,5,1' 

tour_length(3)=B(1,2)+B(2,5)+B(5,4)+B(4,3)+B(3,1) 

tour3='1,2,5,4,3,1' 

tour_length(4)=B(1,3)+B(3,2)+B(2,5)+B(5,4)+B(4,1) 

tour4='1,3,2,5,4,1' 

tour_length(5)=B(1,3)+B(3,5)+B(5,4)+B(4,2)+B(2,1) 

tour5='1,3,5,4,2,1' 

tour_length(6)=B(1,3)+B(3,4)+B(4,2)+B(2,5)+B(5,1) 

tour6='1,3,4,2,5,1' 

tour_length(7)=B(1,2)+B(2,5)+B(5,3)+B(3,4)+B(4,1) 

tour7='1,2,5,3,4,1' 

tour_length(8)=B(1,5)+B(5,4)+B(4,2)+B(2,3)+B(3,1) 

tour8='1,5,4,2,3,1' 

tour_length(9)=B(1,4)+B(4,2)+B(2,5)+B(5,3)+B(3,1) 

tour9='1,4,2,5,3,1' 

tour_length(10)=B(1,4)+B(4,3)+B(3,2)+B(2,5)+B(5,1) 

tour10='1,4,3,2,5,1' 

tour_length(11)=B(1,5)+B(5,3)+B(3,2)+B(2,4)+B(4,1) 

tour11='1,5,3,2,4,1' 

tour_length(12)=B(1,4)+B(4,5)+B(5,3)+B(3,2)+B(2,1) 

tour12='1,4,5,3,2,1' 

tour=[tour1;tour2;tour3;tour4;tour5;tour6;tour7;tour8;tour9;tour10;tour11;tour12] 

tour=cellstr(tour) 

Opt_Tour_Length=min(tour_length) 

Opt_Tour=(find(tour_length == Opt_Tour_Length)) 

Shortest_Tour=tour(Opt_Tour)
