How to solve index bounds problem

Hi

I am just a beginner in MATLAB,Now I am trying to do a code but getting error. i am copying the code,

 function [p1]=element1()
 L=input('Length of pipe =');
 C=input('speed of sound=');
 d=input('Pipe diameter=');
 M=input('Mach number=');
 S=pi*(d/2)^2;
 frequency=0:6:6486;
 K=2*pi*frequency/C;
 Kc=K/(1-M^2);
 Y=C/S;
 KcL=Kc*L;
 KcML=Kc*(L*M);
 p1=zeros(2,2164);
 n=1;
 for i=0:1:1082
 p1(:,(2*n-1):(2*n))=exp(-i*KcML(n)).*[cos(KcL(n)),i*Y*sin(KcL(n));i*sin(KcL(n))/Y,cos(KcL(n))];
 n=n+1;
 end

The error message is

??? Attempted to access KcML(1083); index out of bounds because
 numel(KcML)=1082.

Error in ==> element1 at 27
 p1(:,(2*n-1):(2*n))=exp(-i*KcML(n)).*[cos(KcL(n)),i*Y*sin(KcL(n));i*s

Thanks Advancely

n is 1 when i is 0. n is 2 when i is 1. n is 3 when i is 2. So when i is 1082 what is n going to be?

Thanks what kind of change in my code should I do could you please suggest me?

If I use n=i+1 then i am getting ans of 2x2164 is it ok? I am confused,
