Finding the corresponding number in a matrix

I need to find a number in one column that corresponds with a different column. For example: [1 2 4 6 10 9; 3 5 7 2 8 6], I want the max in column 1, which is ten, I also want to find 8 in the second column.

Did you look up max in the help?

m = [1 2 4 6 10 9; 3 5 7 2 8 6]

m = 2×6

1 2 4 6 10 9 3 5 7 2 8 6

% Find maxes in each of the 2 rows (consisting of 6 columns):
maxesOfRows = max(m, [], 2)

maxesOfRows = 2×1

10 8

% Find maxes in each of the 6 columns (consisting of 2 rows):
maxesOfColumns = max(m, [], 1)

maxesOfColumns = 1×6

3 5 7 6 10 9

what if it was a 5 instead of an 8?

then you would use the code I suggested.

m = [1 2 4 6 10 9; 3 5 7 2 8 6]
[~, idx] = max(m(1,:));
m(2,idx)
