Re: Storing of values in an array

I have a matrix. linedata=[ 1 2 0.0922 ; 2 3 0.4930 ; 3 4 0.3661 ; 4 5 0.3811 ; 5 6 0.8190; 6 7 0.1872 ; 7 8 0.7115 ; 8 9 1.0299 ; 9 10 1.0440 ; 10 11 0.1967 ; 11 12 0.3744 ; 12 13 1.4680 ; 13 14 0.5416 ; 14 15 0.5909 ; 15 16 0.7462 ; 16 17 1.2889 ; 17 18 0.7320 ; 2 19 0.1640 ; 19 20 1.5042 ; 20 21 0.4095 ; 21 22 0.7089 ; 3 23 0.4512 ; 23 24 0.8980 ; 24 25 0.8959 ; 6 26 0.2031 ; 26 27 0.2842 ; 27 28 1.0589 ; 28 29 0.8043 ; 29 30 0.5074 ; 30 31 0.9745 ; 31 32 0.3105 ; 32 33 0.3411 ;]
Out of this, the first column is begin point, and the second column is the destination point. The third column is the distance between the 2 points. I want to find the distance between 1 and all the points. So for the distance between 1 and 4, it should add the value of distance between 1 and 2, 2 and 3, 3 and 4.
Suppose I want to find the distance between 5 and 20. It should add the value of distance between 5 and 4, 4 and 3, 3 and 2, 2 and 19, 19 and 20. Same way if I want to find the distance between 18 and 28, it should add the value of distances between those 2 points alone.
This way I want to find the distance from all the points to all the points.(i.e) from point 1 to all the points, from point 2 to all the points and so forth. How can I do it? Kindly help me in this regard.
Regards
