  /**
   * Logical `and`. Test whether two values are both defined with a nonzero/nonempty value.
   * For matrices, the function is evaluated element wise.
   *
   * Syntax:
   *
   *    math.and(x, y)
   *
   * Examples:
   *
   *    math.and(2, 4)   // returns true
   *
   *    a = [2, 0, 0]
   *    b = [3, 7, 0]
   *    c = 0
   *
   *    math.and(a, b)   // returns [true, false, false]
   *    math.and(a, c)   // returns [false, false, false]
   *
   * See also:
   *
   *    not, or, xor
   *
   * @param  {number | BigNumber | Complex | Unit | Array | Matrix} x First value to check
   * @param  {number | BigNumber | Complex | Unit | Array | Matrix} y Second value to check
   * @return {boolean | Array | Matrix}
   *            Returns true when both inputs are defined with a nonzero/nonempty value.
