The given equation becomes (a^2-b^2-5√(a^2+b^2)+6)+2abi=0 So \(a^2-b^2-5√(a^2+b^2)+6=02ab=0. ① 2 From ②we know that a =0 or b =0. When a =0, from ①we getb^2+5|b|-6=0 . Since bER, (|b|-1)(|b|+6)=0 . Solving we get b= ±1. It ...

While this may be satisfactory, you might prefer to use a simpler tree if it is roughly as good as a more complex tree. For this example, take the simplest tree that is within one standard error of the minimum. That's the default rule used by the cvloss method of ClassificationTree. ...

complex or difficult to implement. When enhanced for operation in practical environments, a significant level of complexity may need to be added but as this example also demonstrates, software designs emphasizing a strong separation-of-concerns can effectively compartmentalize the areas of complexity and...
The frequency-domain representation of a signal carries information about the signal's magnitude and phase at each frequency. This is why the output of the FFT computation is complex. A complex number, x, has a real part, xr, and an imaginary part, xi, such that x=xr+jxi. The magnitude...
