MATLAB: Find the maximum number and its location in the matrix

homeworkmatrix

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 any method 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 🙂

Really really easy, and pretty much the same algorithm any any programming language, like others that you may know. Hint:
[rows, columns] = size(K)
maxValue = -inf;
rowAtMax = 0;
colAtMax = 0;
for column = 1 : columns
  for row = 1 : rows
    if K(........
  end
end
There, it's practically all done for you.
