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