is there an alternative to pdist2 that calculates the distance between a matrices with different column numbers

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).

What if transposing the matrix changes the math for subsequent operations that need column vectors instead of row vectors? Like if i transpose a 3D sphere's coordinates(3x15) for distance calculation to 102x3 array?

Adam did not tell you to transpose the array and save it as such, replacing the original array. He said to transpose it inline, as:

d = pdist2(A, B');

That changes nothing about the original array B for the next time you will use it.

[Adam Danz]

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).

okay I see tha thanks for your help.
