Hello,
Consider a vector with length equals 110.
I want to remove the elements that are correspond to the indices that are larger than 100 (a random threshold), i.e. the elements that correspond from 101 to 110 indices.
Thanks.

Hy, hope I can help with your prob:
A=ones(1,110) % Vector with 110 values
threshold=100; A(threshold:end)=[];
Vector A has then the size 1x99
Hope that is what you are looking for

How it is done with logical comparisons?
For example, A(length(A)>100)=[];

Hy,
in my mind the use of length make no sense in this case!!! Could you please explain me why you want to use "Length" for your problem? Have you tried my advice? Tell me why it doesn't fulfil your problem?
greets, Robert
