le(<=)

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 subset of Y.

Examples

1 2 3 <= 2;
// output
[1,1,0]

1 2 3<=0 2 4;
// output
[0,1,1]

2:3<=1:6;
// output
0 : 1

m1=1..6$2:3;
m1;
#0 #1 #2
1 3 5
2 4 6
m1 le 4;
#0 #1 #2
1 1 0
1 1 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 subset of Y

x=set(4 6);
y=set(4 6 8);

x<=y;
// output
1
x<=x;
// output
1
