Hi there, I have two sets of coordinates such as

startpose = [2,1; 4,5; 6,5; 2,3; 8,9];
endpose = [7,6; 2,4; 5,4; 2,9; 1,6;];

how can I obtain the nearest distance between the "startpose" and the "endpose" so that at the end I will have 5 pair of neareast distance between the two sets, and display which are the pair? Thanks

在 MATLAB Online 中打开

startpose = [2,1; 4,5; 6,5; 2,3; 8,9];
endpose = [7,6; 2,4; 5,4; 2,9; 1,6;];
[distance, index]=pdist2(startpose,endpose,'euc','Smallest',1);
nearestpoints = startpose(index,:)
nearestpoints = 5×2
     6     5
     2     3
     4     5
     4     5
