Hello Those who are in Mapleprimes.

 

I want to know the meaning of [].

That is,

a:=[1,2,3];

b:=a[];

What were returned was 

b:=1,2,3

This result is the same as that obtained from

b:=op(a);

 

What kind of meaning does a[] have?

I want to know the logic of this expression.

Can I ask you about this?

Thank you in advance.
