Hi all,

I would like to determine a logical inequality, but with three conditions imposed. For example, in the case of two conditions the logical inequality would be:

idx = Condition1 < Vector_to_Compare & Vector_to_Compare < Condition2 ;

In the case where I have three vectors I cant write something like

 idx = Condition1 < Vector_to_Compare &  Vector_to_Compare < Condition2 & Vector_to_Compare < Condition3 ;

What would I do in order to impose the three vector condition to the logical index ?

I know it seems that I could possibly combine Condition2 and Condition3, however the one comes from a completely different vector than the other i.e. its completely different in 'nature'.

Donald, I guess the issue is that V2 doesn't have the same size as V1. So in that case the "&" will fail, unless one of them is a scalar.

Konstantinos, what exactly are you hoping to get out of this? If your vectors are different sizes, having a logical indexing vector doesn't really make sense in that context. Can you give us more context on what you have and what you'd like? With an example?
