Hi,

I have an array A of 470 X 1 elements (those are areas e.g.).

I have a matrix B of 470 X 4230 elements (they are 470 X 3x3 blocks). They are also areas. I would like to search throuhout of each of these 3x3 blocks and find the closest area in respect to array A and retrieve that area B and its id.

Does anyone have some clue how I can do this?

Thanks a lot,

How exactly are the "470 X 3x3 blocks" contributed to the "470 X 4230" matrix? How do you define the distance between a scalar and a 3x3 matrix? A definition of the distance is required to determine the "closest".

What is the difference to your question http://www.mathworks.com/matlabcentral/answers/323066-finding-the-closest-area-match-between-matrix-3x3-and-another-data-set?

I assume that this is a duplicate question and you should care about the other thread.
