lt(<)
Syntax
X<Y
Arguments
X and Y is a scalar/pair/vector/matrix/set. If X or Y is a pair/vector/matrix, the other is a scalar or a pair/vector/matrix of the same size.
Details
If neither X nor Y is a set, return the element-by-element comparison of X<Y. If X and Y are sets, check if X is a proper subset of Y.
Examples
$ 1 2 3 < 2;

$ 1 2 3<0 2 4;
[0,0,1]
$ 2:3<1:6;

Set operation: If X<Y then X is a proper subset of Y
$ x=set(4 6);
$ x;
set(6,4)
$ y=set(8 9 4 6);
$ y;
set(6,4,9,8)
$ x<y;
1
// x is a proper subset of y
$ y<x;
0
// y is not a proper subset of x
$ x<x;
0
// x is not a proper subset of x
