MATLAB: How i can find the Entropy for 3 probabilities by matlab

entropyfor loopMATLAB

Hello Every one
Im trying to calculate the entropy for three random values as shown in the following script , but it gives me an error . could any one please help me to find the correct answer. Many thanks.
if true 
p00=[0.1 0.2 0.3 0.4 0.5 0.6 0.7  ];
 p01=[0.1 0.2 0.3 0.4 0.5 0.6 0.7  ];
 p02=[0.1 0.2 0.3 0.4 0.5 0.6 0.7  ];
for i=1:length(p00)
    for j=1:length(p01)
        for k=1:length(p02)
        p03=1-p00(1,i)-p01(1,j)-p02(1,k)
    H(i,j,k) = real((-p00(1,i).*log2(p00(1,i))-(p01(1,j)).*log2(p01(1,j))-p02(i,j,k).*log2((p02(i,j,k)))-p03(i,j,k).*log2((p03(i,j,k)))))
    end
    end
end
  end

Hi, first thing which is incorrect in your code is that you are trying to access p02(1,1,2) however p02 is 1x7 matrix. Similarly check for other syntaxes also. Second, I am not getting what are p00, p01 and p02. What is meaning of a vector here?
