find Euclidean distance without the for loop

I was finding the Euclidean distance using the for loop, I need help finding distance without for loop, and store into an array.

i'm storing the value in distance1 and distance2 variable. I need to convert it into an array.

distance12 = sqrt(sum(([centroid1,centroid2] - permute(dataset,[1,3,2])).^2,3));
