                 Summary: Complex numbers in array gives NaN => Power operator
operating on complex numbers results in NaN when broadcasting

Follow-up Comment #2:

Bumping the version up to "dev" since this is still present.  The issue seems
to be related to broadcasting and I have changed the Summary to reflect that.

A simple test case with broadcasting that fails is


([1;0]*j) .^ [1, 0]
ans =

   0.0000 + 1.0000i   1.0000 +      0i
        0 +      0i      NaN -    NaNi


But if the matrices are full and there is no broadcasting then this works


([1,1; 0,0]*j) .^ [1, 0; 1, 0]
ans =

   0 + 1i   1 + 0i
   0 + 0i   1 + 0i
