  /**
   * Calculates the power of x to y element wise.
   *
   * Syntax:
   *
   *    math.dotPow(x, y)
   *
   * Examples:
   *
   *    math.dotPow(2, 3)            // returns number 8
   *
   *    const a = [[1, 2], [4, 3]]
   *    math.dotPow(a, 2)            // returns Array [[1, 4], [16, 9]]
   *    math.pow(a, 2)               // returns Array [[9, 8], [16, 17]]
   *
   * See also:
   *
   *    pow, sqrt, multiply
   *
   * @param  {number | BigNumber | Complex | Unit | Array | Matrix} x  The base
   * @param  {number | BigNumber | Complex | Unit | Array | Matrix} y  The exponent
   * @return {number | BigNumber | Complex | Unit | Array | Matrix}                     The value of `x` to the power `y`
