I have a positive semi-definite, real matrix, but the output from scipy matrix square root is complex (although the imaginary parts are zero to machine precision). I think it's a bit odd, since the keep_it_real logic should force it to real, but something's obviously gone a bit awry...

However, if I divide instead of multiply by b, Matlab can no longer determine the sign of the square root. This is particularly confusing because Matlab had no additional information regarding b in the first example. clearall symsbeta c f2 sigma f1...
