Previously, only real parts were compared; this can be trivially achieved by wrapping the operands in real(). + ** The automatic simplification of complex computation results has changed. Octave will + now simplify any complex number with a zero imaginary part or any complex matrix + with all elements having zero imaginary part to a real value. Previously, this was done + only for positive zeros. + Note that the behavior of the `complex' function is unchanged and it still + produces a complex value even if the imaginary part is zero. + ** As a side effect of code refactoring in liboctave, the binary logical operations are now more easily amenable to compiler optimizations and are thus significantly faster.
