what is the problem with the second 'IF' loop ? Program terminates after entering into the loop.

I am able to enter into the second "IF" but the simulink program terminates after executing the lines in the second "IF" condition. Simulink runs for the required time without the second "IF" condition.

function [Out] = LMAImplementation_Motor(In)

persistent eWithNoChange eWithDeltaL eWithDeltaK

e = In(1); 

L = In(2);   

K = In(3);   

Clock = In(4);

if (0.0000 <= Clock) && (Clock <= 0.9999)

      deltaK = 0; deltaL = 0;

      eWithNoChange(end+1) = e;

      [m,n] = size(eWithNoChange);

end

if n == 30001         %THIS LINE WAS BOLD

      eWithNoChange(:,1) = [];

      sizeofeWithNoChange = size(eWithNoChange)

end

if (1.0000 <= Clock) && (Clock <= 1.9999)

      deltaL = L*0.1; deltaK = 0;

      eWithDeltaL(end+1) = e;

end

Out = [deltaL,deltaK,Clock];

The issue got solved, As I didn't define the variable "n" the program gets terminated, after defining the variable there is no more issue.
