MATLAB: Removing elements from matrix

Question

Hi everyone,

I was wonderning is there an easy way to remove some of the elemetts from matrix. I have a data array data(300×2) and I want to remove all rows that have the value in the second column smaller than 0.18.

I tried something like

data=data(data(:,2)<0.18);

and similar combinations but it doesn't work.

Thank you in advance for any advice you can offer.

Answer 1

data=data(data(:,2)>=0.18,:);

ADDED after Marin's comment

simple example

data1 =[...
2     3
5     8
10     3
4     6
6     7]
data2 =[...
9     2
10     2
6     3]
data1(ismember(data1(:),data2(:))) = nan
