Power: ^

If b and r are two scalars, then b^r is b raised to the power of r: .

If the base b is negative and the exponent r is a fraction, or either b or r is complex, the result is the principal value of the (multi-valued) power . For example

  2 ^ (5)
      32
  3 ^ (-2)
      0.1111111111
  9 ^ (1/2)  
      3
  (-3) ^ (1/2)
      0 + 3i

If A is a square matrix, and
