Hello together,
i want to find a solution for my problem:
I have a 230x2 Matrix, which contains different numbers. I want the programm to tell me, which row contains numbers higher than 400.
How can i do that?
I tried the "find"-function but it didnt bring me to a useful result.
Thank you.
MG.

Ran in:
"I tried the "find"-function but it didnt bring me to a useful result."
It works for me:
% Fake data:
M = randi(9,7,2);
M(5,1) = 789
M = 7×2
3 8 2 3 9 7 6 5 789 6 5 2 7 9
% Find row:
[R,~] = find(M>400)
R = 5
