Creating an equation library (Updated 03-FEB-2017)

Yes I see what you are saying - the matrix is symmetric, and Wolfram alpha gives a purely real solution. Even with complex checked off in Home settings, and use i checked off in CAS settings it returns the complex elements in the U matrix.

But . . . presume the output is stored in L1, then, in CAS, L1(1)*diag(L1(2))*TRN(L1(3)) returns the original matrix - - so couldn't one argue that the complex SVD output is also correct?
