Write for loop results in a matrix

I have an A(:,2) matrix with some x-y coordinates, and B(:,2) matrix with a list of gauge stations coordinates. So, I want to find the nearest gauge station for each line of A. I could get to the code above, but I couldn't find a way to put this in a loop which write the nearest B point for each A line in 'nstation'
dist=bsxfun(@hypot,B(:,1)-A(1),B(:,2)-A(1));
nstation = B(dist==min(dist),:);

X = B(:,1) - A(:,1).'; % >= R2016b ! Arithmetic expanding
Y = B(:,2) - A(:,2).';
dist2 = sum(X.^2 + Y.^2);
Now you can use this matrix to find the minimal distances. Use pdist for a more efficient calculation, which considers the symmetry.
