MATLAB: Using 2 indexs for loop

for loop

Hi
how can i optimize this loop, if i want to include another indexing
mHome is an 15001×28 array
mBall is an 15001×3 array
for i=1:length(mHome) 
 output1(i,1)=pdist([mHome(i,1:2);mBall(i,1:2)]);
 output1(i,2)=pdist([mHome(i,3:4);mBall(i,1:2)]);
 output1(i,3)=pdist([mHome(i,5:6);mBall(i,1:2)]);
 output1(i,4)=pdist([mHome(i,7:8);mBall(i,1:2)]);
 output1(i,5)=pdist([mHome(i,9:10);mBall(i,1:2)]);
 output1(i,6)=pdist([mHome(i,11:12);mBall(i,1:2)]);
 output1(i,7)=pdist([mHome(i,13:14);mBall(i,1:2)]);
 output1(i,8)=pdist([mHome(i,15:16);mBall(i,1:2)]);
 output1(i,9)=pdist([mHome(i,17:18);mBall(i,1:2)]);
 output1(i,10)=pdist([mHome(i,19:20);mBall(i,1:2)]);
 output1(i,11)=pdist([mHome(i,21:22);mBall(i,1:2)]);
 output1(i,12)=pdist([mHome(i,23:24);mBall(i,1:2)]);
 output1(i,13)=pdist([mHome(i,25:26);mBall(i,1:2)]);
 output1(i,14)=pdist([mHome(i,27:28);mBall(i,1:2)]);
end
% I have tried this but it does not work
for i=1:length(mHome) 
    for k=1:size(mHome,2)
 output1(i,k)=pdist([mHome(i,k);mBall(i,1:2)]);
    end
 end

Best Answer

for i=1:length(mHome) 
    for k=1:2:size(mHome,2)-1
       output1(i,k)=pdist([mHome(i,k:k+1);mBall(i,1:2)]);
    end
 end
