Matlab Function to produce data from points

Hi

The question i have is say i have a starting position (x and y) (2D)

following that i have 2 colums of randomly generated points to act as x and y (rand(20,1),rand(20,1) for other coordinates

function inputs(x,y,c1,c2) if that makes sense (where c1= rand(20,1 and c2= rand(20,1)

with this infomation im looking to calcualte some data resulting in from the starting position the closest point from the c1 and c2 and from that positon the next one and next one until i find a 'path' that would display for example (1,5,2,6,9,17,13...) to find the shortest distance between all points

is there any possibility to do this?

any advice appreciated

The concatenation of the shortest paths is not necessarily the shortest path over all points, is it?

But of course it is possible to do, what you are asking for. Use pdist() and sort the values.

yeah thats okay im just looking to start find the cloest and then find the closest too that one and so on until they are all 'visited'

coming in to using pdist() with my c1 and c2 i require them to be 2 sperate inputs in the function but what would be the way to say for example for 3 rand points

0.323 0.731

0.532 0.421

0.853 0.312

'combine' them to become

1= (0.323,0.731)

2= (0.532,0.421)

3= (0.853,0.312)

and given them an 'id' number if you could possible help with that?

However thanl you for your response also i will look into using the pdist()
