I think that it follows the rules of "items". The list of names to the left
are considered items and matched with the items on the right of the copula.

The current verbs for calculating covariance and correlation in the
stats/base/multivariate.ijs script, are dyadic and designed to calculate
the cov/corr between 2 variables
e.g.
load 'stats'
X=: 1 1 1 1 2 2 2 2 3 3 3 3
Y=: 1 2 2 3 5 5 6 7 10 11 11 12
Z=: 1 1 2 2 4 6 5 4 8 7 9 10
X cov Y
Sure, there are different ways to perform a task, for example,
2&* 1 2 3
2 4 6
+: 1 2 3
2 4 6
What do you mean by "the rest of that"?

All [1] needed was
add=:4 :0
((0{::y),'__x')=: ".1{::y
)
But I don't really follow the rest of that.

The assignments are a consequence of J's agreement; see [0] for example.
If one wants the effect of 'a b c' =:i.3 4 5 using the verb is (or a
similar verb) then one can use 'a b c' is i.3 4 5 :)
How is 'abc' is"0 i.3 4 5 useful? I do not know... Who knows?
How is the verb is (or a simi
How is "is" more useful than from x=: y
what is interesting is that
'abc' is "0 i.3 4 5 displays the i.3 4 5 array but the value of abc
appears as : although a, b, c correspond to
(<0 1 2; 3; 4){i. 3 4 5
19 39 59
In the use of "is" in this case it appears that it
whereas 'abc' =: i. 3
No, I am asking *how* it is useful.
