How to perform a single Matrix calculation and store result back into a vector or matrix

Hi, Everyone

I have written a code which calculates weighted distance in a single matrix. (similar to euclidean distance). I need to know how to store my results back into a matrix or vector instead of displaying it n times.

Here is my code

///////////////////////////

i=1; 
j=2; 

for i=1:4

for j=2:5

      if((i~=j)&&(i<j))
  d=0;    
       for k=1:6

       sum=(data(j,k)-data(i,k))^2;

       d=d+sum;

            end

d=(0.25*d)^(1/2)

       end       
  end
  ////////////////////
  end

For example if I have a 5x6 matrix as given below

85 92 45 27 31 0
85 64 59 32 23 0
86 54 33 16 54 0
91 78 34 24 36 0
87 70 12 28 10 0

my results are displayed as

d =

16.3478

d =

23.6590

d =

9.8362

d =

22.4666

d =

22.3271

d =

16.5076

d =

24.6678

d =

15.7321

d =

26.3534

d =

17.7200

But I would like to store as

d=[ 16.3478; 23.6590; 9.8362; 22.4666; 22.3271; 16.5076; 24.6678; 15.7321; 26.3534; 17.7200]

Please If anyone could help me.

The line

////////////////////

is not valid in your code, and would cause your code to fail.

1. "i=1; j=2;" is not needed based on your code.
2. Don't use "sum" as the variable name. sum() is a built-in function.

Your code can be improved as the following:

data=rand(5,6);
[M,N]=size(data);
d=zeros(M*(M-1)/2,1);
count=0;
for i=1:M-1
    for j=2:M
        if((i~=j)&&(i<j))
            count=count+1;    
            for k=1:N
                d(count)=d(count)+(data(j,k)-data(i,k))^2;
            end
            d(count)=(0.25*d(count))^(1/2);
        end       
    end
end

Thank You very much.
