Find the maximum value and its location from a matrix using two nested loops

58 views (last 30 days)
Hi,
Right now I have this matrix K
K =
-3 -8 6 -3 -8 6 9 24 -18
-5 10 -9 -5 10 -9 15 -30 27
8 4 9 8 4 9 -24 -12 -27
-9 -24 18 12 32 -24 3 8 -6
-15 30 -27 20 -40 36 5 -10 9
24 12 27 -32 -16 -36 -8 -4 -9
9 24 -18 -15 -40 30 0 0 0
15 -30 27 -25 50 -45 0 0 0
-24 -12 -27 40 20 45 0 0 0
I wonder how I can use two nested loops to find the maximum number and its location from this matrix.
It would be great if anyone can help me with this
Thank you very much :)

you can do it as follow:
MaxValue = -Inf;
row = 0;
column = 0;
for i = 1:size(K, 1)
for j = 1:size(K, 2)
if K(i, j) > MaxValue
MaxValue = K(i, j);
row = i;
column = j;
end
end
end
