How do we write a code for a periodic intermittent scalar function?

I would like to write a code of an periodic intermittent bounded control. I've tried to write it as a piecewise function but its not giving me type of output I want. Can someone help please? This what I have written

K = 0:0.01:1;
Pk =[];
m = 4; h = 0.1; T = 0.05;
for k = 1:length(K)
    if (K(k) >= m*T & K(k) < m*T + h)
        pk = 4; 
    elseif (K(k) >= m*T + h & K(k) < (m+1)*T)
        pk = 0;
    end
    Pk = [Pk pk];
end

you need to explain what result you are expecting and why do you think the above code is wrong

This what it is giving me.

However, I want something like this

And what do you expect instead?

Here is what I wanted. I've solved it.

clear all; close all; clc;

N = 0.2;
h = 0.5;
n= 0:25;
t = 0:0.001:5;
for i = 1:length(n)
   for j = 1:length(t)
      if (t(j) >= n(i)*N)&(t(j) < (n(i) + h)*N)
          k(j) = 2;
      elseif (t(j) >= (n(i) + h)*N)&(t(j) < (n(i) + 1)*N)
          k(j) = 0;
      end
   end
end
plot(t,k,'linewidth',2)
axis([0 5 0 2.5]);
