How can I record value once condition is satisfied by searching a matrix?

1 view (last 30 days)
Hello!
I have a 2234x42 matrix. I would like to search the 2nd column of the matrix for every time a condition is met. Say for a value less than or equal to some tolerance. I also would like to record values in the 4th and 5th column at that condition as well. Does anyone have some insights on how to approach this?
I tried to do something like:
for k = 1:size(state,1)
S = cell(find(state(k,2)<= 1E-4));
end
However, I do not need the position, I need to grab the actual value. Thanks in advance!
Thanks!

newMatrix=yourMatrix(yourMatrix(:,2)<=tol,4:5);
