Event columns can be used in math expression which can be used everywhere an event function is needed. For example one can write

    5 < sqrt (pwr (Column ("Amplitude(0)"), 2) +
              pwr (Column ("Amplitude(1)"), 2) )
    \begin{verbatim}
    to define an event condition which checks whether the vector 
    sum of the amplitudes of two events is larger than 5.

enum operation

Math operations supported by the function.

Arc tangent (2 arguments)

Complex number in polar notation

Math(const Function& f, operation op)

Creates an math expression of a single value (unary operator).

Math(const Function& f1, const Function& f2, operation op)

Creates an math expression of two values (binary operator).

virtual Math* Copy() const

Returns a copy of the event column math object. This method must be overriden by all descendents.

Returns:: event copy

virtual bool Evaluate(const Argument& arg, Value& val) const

Returns the evaluated math expression.

Returns:: true if successful
Parameters:: arg - Event argument list
val - Fucntion value (return)

Math()

Default constructor

This class has no child classes.
