WebJun 20, 2024 · The bitwise not (~) operator flips the bits in the variable. In this case, the binary representation of 0, “00000000”, was transformed into -1, “11111111”. While the (~) operator works by flipping bits, the logical negation operator (!) is a logical operator that works on bool values, changing true to false or false to true. WebVectorized "dot" operators. For every binary operation like ^, there is a corresponding "dot" operation .^ that is automatically defined to perform ^ element-by-element on arrays. For example, [1,2,3] ^ 3 is not defined, since there is no standard mathematical meaning to "cubing" a (non-square) array, but [1,2,3] .^ 3 is defined as computing the elementwise …
