Examples of org.apache.commons.math3.complex.Complex.subtract()

org.apache.commons.math3.complex.Complex.subtract()
Returns a {@code Complex} whose value is{@code (this - subtrahend)}. Uses the definitional formula
```
  (a + bi) - (c + di) = (a-c) + (b-d)i  
```
If either {@code this} or {@code subtrahend} has a {@code NaN]} value in either part,{@link #NaN} is returned; otherwise infinite and {@code NaN} values arereturned in the parts of the result according to the rules for {@link java.lang.Double} arithmetic. @param subtrahend value to be subtracted from this {@code Complex}. @return {@code this - subtrahend}. @throws NullArgumentException if {@code subtrahend} is {@code null}.
