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;
// output
[1,0,0]
1 2 3<0 2 4;
// output
[0,0,1]
2:3<1:6;
// output
0 : 1
m1=1..6$2:3;

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