Hi, A very similar problem was discussed here in length. You'll find there numerous hints how to make your code faster. Cheers Wozai -- Sent from:

Hello, d = zeros(n,1); for ii=1:n; //SqDist = (X-X(i))^2 + (Y-Y(i))^2 + (Z-Z(i))^2; SqDist = (X-X(ii)).*(X-X(ii)) + (Y-Y(ii)).*(Y-Y(ii)) + (Z-Z(ii)).*(Z-Z(ii)); SqDist(ii)= []; d(ii)= sqrt(min(SqDist)); end; some comments: * preallocate matrix * avoid unnecessary assign
