The unary operators take a single operand of any dimensions and operate on each of its elements independently. The unary operators are:
-
Inverts the sign of each element.
+
No change.
NOT
Logical inversion: each positive value becomes 0 and each zero or negative value becomes 1.
Examples:
-{1, -2; 3, -4} | ⇒ | {-1, 2; -3, 4} |
+{1, -2; 3, -4} | ⇒ | {1, -2; 3, -4} |
NOT {1, 0; -1, 1} | ⇒ | {0, 1; 1, 0} |
