ge

Syntax

ge(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 Y is a subset of X.

Examples

$ 1 2 3 >= 2;
[0,1,1]

$ 1 2 3 >= 0 2 4;
[1,1,0]

$ 2:3>=1:6;
1 : 0

$ m1=1..6$2:3;

Set operation: If X>=Y then Y is a subset of X

$ x=set(4 6);
$ x;
set(6,4)
$ y=set(8 9 4 6);
$ y;
set(6,4,9,8)

$ y>=x;

// x 是 x 的子集
