     11    * Get the imaginary part of a complex number.
     12    * For a complex number `a + bi`, the function returns `b`.
     13    *
     14    * For matrices, the function is evaluated element wise.
     15    *
     16    * Syntax:
     17    *
     18    *    math.im(x)
     19    *
     20    * Examples:
     21    *
     22    *    const a = math.complex(2, 3)
     23    *    math.re(a)                     // returns number 2
     24    *    math.im(a)                     // returns number 3
     25    *
     26    *    math.re(math.complex('-5.2i')) // returns number -5.2
     27    *    math.re(math.complex(2.4))     // returns number 0
     28    *

     34    *            A complex number or array with complex numbers
     35    * @return {number | BigNumber | Array | Matrix} The imaginary part of x
