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

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
