Change for cross function from R2019a to R2019b

I see that to perform the calculation done by R2019a's cross function I now have to do conj(cross). I see that https://www.mathworks.com/help/matlab/ref/cross.html has been updated, but where else is this notable change documented ?

Interesting change, although I have never had the need to take the cross product of complex vectors myself.

For instance, in the time harmonic formulation (using complex numbers and replacing E with E*e^{i w t}) of Maxwell equations in a 3d domain, the boundary conditions (Dirichlet or Neumann) are formulated with a cross product.

The update 4 is still returning the complex conjugate :)

Incorrect Code Generation: cross returns complex conjugated results for complex inputs (2088279)

try to run the code as they say:

>> a = magic(3) + 1i.*magic(3);

>> b = ones(3) + 1i.*ones(3);

>> c = cross(a,b)

c =

0.0000 - 2.0000i 0.0000 - 8.0000i 0.0000 +10.0000i

0.0000 - 8.0000i 0.0000 +16.0000i 0.0000 - 8.0000i

0.0000 +10.0000i 0.0000 - 8.0000i 0.0000 - 2.0000i
