A = rand(47, 47, 3);

B = rand(1, 456 3);

AB = reshape(A, 47*47, 1, 3) - B;

Dist = vecnom(AB, 2, 3);

And now you want to find the minimal values in each column. Afterwards you can use ind2sub to convert the linear indices back to the indices of A.

Another option is a simple loop:

Result = zeros(size(A));

for row = 1:47

for col = 1:47

dist = vecnorm(A(col, row, :) - B, 2, 3);

[~, index] = min(dist);

Result(col, row) = index;

end

end
