Extracting data from a matrix for a particular threshold

Hi,

I have a data matrix (442 x 442) which represents pairwise correlations (Cij). I have values from -1 to 1 and I would like to identify the rows and columns with values greater than 0.6 and also less than -0.6. I've tried a few solutions but I'm not having any luck.

Any form of guidance will be much appreciated.

Thank you,

Akash

Read about find

idx = A>0.6 | A<-0.6 ;

Hi,

Thank you for your answer. When I ran the code, it returned binary values 1 or 0, which is expected. If I wanted then print the row and column number, how would I do that? For example, row 2, column 9

I read about find , but I'm still not clear on how to do the above.

you can extract the respective values using A(idx) . if you want indices use find(idx). They are logicals.
