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;
m1;
#0 #1 #2
1 3 5
2 4 6
m1 lt 4;
#0 #1 #2
1 1 0
1 0 0
m2=6..1$2:3;
m2;
#0 #1 #2
6 4 2
5 3 1
m1<m2;
#0 #1 #2
1 1 0
1 0 0

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
