ne(!=)
Syntax
X != Y
or
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, conduct the element-by-element comparison of X and Y; return 1 if the elements in X and Y are not the same.
If X and Y are sets, check if X and Y are not identical.
Examples
1 2 3 != 2;
// output
[1,0,1]
1 2 3 ne 0 2 4;
// output
[1,0,1]
1:2 != 1:6;
// output
0 : 1
m1=1..6$2:3;
m1;
#0 | #1 | #2 |

t = table(`A`B`M`B`A`M as sym, 10.1 11.2 11.3 12 10.6 10.8 as val)
select * from t where nullIf(sym, `M)<>NULL
// output

B 11.2
B 12
A 10.6

Set operation: If X!=Y then X and Y are not identical
x=set(4 6);
y=set(4 6 8);
x!=y;
// output
1
x!=x;
// output
0
