How to find the distance between pionts? Pls Help

[Rihanna]

Hello My Friends

I am trying to find the distance from 1,1 to all other points then from 2,1 to all other points then from 3,1 to all other points ...........etc, until from 3,3 to all other points .
I used this function in Matlab and i got the answer

arclen = distance('gc',[37,-76],[37,-9]);arclen1 = distance('gc',[37,-76],[37,-9]) and i got the answer,

However i need some help to write the full program for these 9 points, could you please try to help?



Note: all the points are real on the map an has ( longitude) and ( latitude ).


regards

You have 9 locations (loca = 1 through 9).

You'll create 2 nested FOR-NEXT loops.

FOR counter_a = 1 to 9
FOR counter_b = (counter_a + 1) to 9
(add a routine to skip cases where counter_a = counter_b)

At the beginning of the program you stored the x values in x(loca) and the y values in y(loca).

Calculate distance between the current pair of points x(counter_a), y(counter_a) and x(counter_b), y(counter_b).

Store in an array named 'dist (counter_a, counter_b)'

That's the general idea. You'll have to fill in the details.
