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;

$ 1 2 3==0 2 4;
