find index conditional on two vectors
显示 更早的评论
Hi,
I have two vectors =
resp = [1 2 3 1 1 2 3 3 3 1];
fing = [1 2 1 2 1 1 1 2 2 1];
How do I find the indices of resp where resp ==1 and fing ==1 (for instance in this example, this would be index 1 of resp, index 5 of resp, and index 10 of resp)?
Many thanks

find( resp == 1 & fing == 1 );
If you don't need the actual linear indices though then the logical vector returned by just
resp == 1 & fing == 1
will work as an index into other arrays if needed and is more efficient than finding the linear indices first.

clc; clear all ;
resp = [1 2 3 1 1 2 3 3 3 1];
fing = [1 2 1 2 1 1 1 2 2 1];
idx1 = find(resp==1)
idx2 = find(resp==2)
