Extracting data from a matrix for a particular threshold
显示 更早的评论
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 ;

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