Detailed Description

template<typename arg>
class ParsedFunction< arg >

ParsedFunction.

This function type contains a double - valued function string like $var1=atan(.5); sin(cos(atan(asin(exp(X+var1)))))$. When the operator () is called, $X$ is replaced with the argument of the operator call and the function string is parsed and evaluated.
