le
Syntax
le(X, Y) or X<=Y
Arguments
X / 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 both 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 |

| 5 | 3 | 1 |
m1<=m2;| #0 | #1 | #2 |

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
