eq

Syntax

eq(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 and Y.

If X and Y are sets, check if X and Y are identical.

Examples

1 2 3 == 2;
// output
[0,1,0]

1 2 3==0 2 4;
// output
[0,1,0]

1:2==1:6;
// output
1 : 0

m1=1..6$2:3;
m1;
#0 #1 #2
1 3 5
2 4 6 
m1 == 4;
#0 #1 #2
0 0 0
0 1 0 
m2=6..1$2:3;
m2;
#0 #1 #2
6 4 2
5 3 1 
m1==m2;
#0 #1 #2
0 0 0
0 0 0

Set operation: If X==Y then X and Y are identical.

x=set(4 6)
y=set(4 6 8);

x==y;
// output
false
x==x;
// output
true
