Martix are updating without entering into "for" loop,

I Want to eWithDeltaL, eWithDeltaK to be updated during the time intervals mentioned.

function [out] = motor(In)

e = In(1);

%there is some other code 

Clock = In(4);

clock = int64(Clock);

for clock = 0:0.999 

      eWithNoChange = [];

      eWithNoChange(end+1) = e;
  end
  for clock = 1.0000:1.999
      deltaL = L*0.1;
      eWithDeltaL = [];
      eWithDeltaL(end+1) = e;
  end
  Out = [deltaL,deltaK,clock]

It is being updated: it is having the previous value(s) removed from it and the new value is being stored in it, every iteration of the loop.

What you probably want is to initialize the array once before the loop instead of initializing it in every iteration of the loop. For example,

eWithNoChange = [];
for clock = 0:0.999 
      eWithNoChange(end+1) = e;
end

Side note:

When you have a for loop, after the loop is finished executing, the index variable (such as clock) is left as the last value that was assigned to it. For example,

for I = 1 : 10
  disp(I);
end

then since 10 was the last value assigned to I, after the loop, I will be left as the value 10 .

I made the changes you mentioned ,but new column is added to matrix without considering the "for" loop.

function [Out] = LMAImplementation_Motor(In)

persistent eWithNoChange eWithDeltaL

Clock = In(4);

clock = int64(Clock);

for clock = 0:0.999

    deltaK = 0; deltaL = 0;

    eWithNoChange(end+1) = e;

end

for clock = 1.0000:1.999

    deltaL = L*0.1;

    eWithDeltaL(end+1) = e;

end

Out = [deltaL,deltaK,Clock];
