Distance between two set of points in space

So I have a set of points in a matrix A 10x3 ( i.e 10 points with x,y,z coordinates) and another set of points in a matrix B 10x3. I want to find the distance between each point of A with each point of B whitout using a for loop.
Normally I would fix a point in A and compute all the distances with the points in B and then choose another point in A and do the same and so on. Is there a way to do it directly from the matrix A and B whitout a loop ?

distances = pdist2(A,B);

Why no loop? Below is oneliner but has an internal loop.
