|
* Logical `not`. Flips boolean value of a given parameter.
|
|
* For matrices, the function is evaluated element wise.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.not(x)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.not(2) // returns false
|
|
* math.not(0) // returns true
|
|
* math.not(true) // returns false
|
|
*
|
|
* a = [2, -7, 0]
|
|
* math.not(a) // returns [false, false, true]
|
|
*
|
|
* See also:
|
|
*
|
|
* and, or, xor
|
|
*
|
|
* @param {number | BigNumber | bigint | Complex | Unit | Array | Matrix} x First value to check
|
|
* @return {boolean | Array | Matrix}
|
|
* Returns true when input is a zero or empty value.
