I was wondering if there is a built in matlab fucntion that calculates the distance between two arrays that don't have the same column number like in pdist2? For example if matrix A was 102x3 and Matrix B was 3x15, is there a MATLAB function that can do this calculation for me or do I need to use nested for loops?

You just need to transpose B
d = pdist2(A, B');
d(i,j) is the distance between A(i,:) and B(:,j).

As evidence of what John said, note the indexing I used in my answer to describe d.
d(i,j) is the distance between A(i,:) and B(:,j).
