Hi: I have two set of 2D scatter points, says A and B, I need the minimun value of each points in A to B. for example, the size of A and B are 100*2, and below are my codes:
for i=1:1:100 ppdist=((A(j,1)-B(:,1)).^2+(A(j,2)-B(:,2)).^2).^0.5; result(i)=min(ppdist); end
however, if the size of A and B are significantly large, for example: 1 million for each, the calculation cost significantly large amount of time.
so I want know if there is anyway to optimize this calculation?
Thanks Yu
