/**
* 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 | Complex | Unit | Array | Matrix} x First value to check
* @return {boolean | Array | Matrix}
* Returns true when input is a zero or empty value.
