use of short Circuit operator

Hi, How can I use short circuit operators(&&) in vector variable?

You cannot. && can only be used for scalars.

Note that if you are trying to code something like

if vector1 && vector2

then the "if" would be considered true only if all values in "vector1 && vector2" evaluated to true, because that is how "if" behaves on vectors and matrices, as if there was an all() wrapped around everything:

if all(vector1 && vector2)

With some minor thought on the meaning of "&" you can see this would be the same as

if all(all(vector1) && all(vector2))

which could be written more briefly as

if all(vector1) && all(vector2)

which is allowed.
