Have one array follow another array with a threshhold
显示 更早的评论
Hi there! I've got two arrays and I want to put a threshhold on one of them and have the other array follow it (see example down below). After the threshhold is done, I'd like my array A1 follow the new A2, meaning that the first 3 values of A1 should be removed.
Any tips on how to do this?
A1 = [1 4 5 8 2 2 4];
A2 = [2 5 8 15 18 24 23]
A2Thresh = A2 < 10 | A2 > 30;
A2(A2Thresh) = [ ]

Use the same approach for A1 as well.
A1 = [1 4 5 8 2 2 4];
A2 = [2 5 8 15 18 24 23];
A2Thresh = A2 < 10 | A2 > 30;
A2(A2Thresh) = []
A1(A2Thresh) = []
Edit - This works only if both A1 and A2 have same size

When you perform this operation
FLWAll(FLWTHRESH) = [];
The number of elements of FLWALL are reduced, and you can not delete the indices who are greater are the number of elements of FLWALL, which the logical vector VTHRESH might contain.
Thus the error "Matrix index is out of range for deletion".
To resolve the issue, combine the both the conditions together and perform the deletion -
VTHRESH = VAll < 18.69;
VAll(VTHRESH) = [];
FLWTHRESH = FLWAll < 0.10 | FLWAll > 0.30;
FLWAll(FLWTHRESH | VTHRESH) = [];
