Get row number with certain data in it

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.

"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
