ne

Syntax

ne(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 both 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
1 3 5
2 4 6 
m1 != 4
#0 #1 #2
1 1 1
1 0 1 
m2=6..1$2:3;
m2;
#0 #1 #2
6 4 2
5 3 1 
m1 ne m2;
#0 #1 #2
1 1 1
1 1 1

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
