Hi, everybody
I'm trying to find the nearest values from a array inside a matrix. Example:
Array = [12, 16, 300, 200, 250, 380, 145, 6, 8, 10, 12, 100, 16, 440]; %array with 14 elements
Matrix = [15, 20, 310; 1000, 500, 1; 146, 10, 11; 5, 23, 800; 600, 100, 50]; %matrix 5x3
but when a try:
for i=1:size(Array,2)
[~,ID] = min(abs(Matrix - Array(i)),[],1);
end
The ID have just 3 elements, not 14. I don't understand why. Anybody could explain to me. please.
Att,
Paulo

for i=1:size(Array,2)
[r{i},c{i}] = find(abs(Matrix-Array(i))==min(abs(Matrix(:)-Array(i))));
end

Man, you just destroyed the question! That was incredible!! Thank you very much!

You are overwriting the value of ID with each pass through your loop, so you only see the value for the last pass.
If you want the value for every pass then you need to assign ID(i) in the loop

@Jon thank you for the clarification! You helped me to solve the problem with your main answer. Thank you!!
