Member Function Documentation

virtual Func1& duplicate ( ) const

inlinevirtual

Duplicate the current function.

This duplicates the current function, returning a reference to the new malloced function.

Reimplemented from Func1.

Definition at line 964 of file Func1.h.

virtual doublereal eval ( doublereal  t ) const

inlinevirtual

Evaluate the function.

Reimplemented from Func1.

Definition at line 969 of file Func1.h.

doublereal operator() ( doublereal  t ) const

inherited

Calls method eval to evaluate the function.

Definition at line 55 of file Func1.cpp.

References Func1::eval().

Func1 & derivative ( ) const

virtualinherited

Creates a derivative to the current function.

This will malloc a derivative function and return a reference to the function.

Reimplemented in Composite1, Ratio1, PlusConstant1, TimesConstant1, Product1, Diff1, Sum1, Const1, Pow1, Exp1, Cos1, and Sin1.

Definition at line 66 of file Func1.cpp.

Referenced by Sum1::derivative(), Diff1::derivative(), Product1::derivative(), TimesConstant1::derivative(), PlusConstant1::derivative(), Ratio1::derivative(), and Composite1::derivative().

bool isIdentical ( Func1 &  other ) const

inherited

Routine to determine if two functions are the same.

Two functions are the same if they are the same function. This means that the ID and stored constant is the same. This means that the m_f1 and m_f2 are identical if they are non-null.

Definition at line 73 of file Func1.cpp.

References Func1::isIdentical().

doublereal c ( ) const

inherited

accessor function for the stored constant

accessor function for the returned constant

Definition at line 98 of file Func1.cpp.

Referenced by Func1::setC().

void setC ( doublereal  c )

inherited

Function to set the stored constant.

Definition at line 104 of file Func1.cpp.

References Func1::c().

Func1 & func1 ( ) const

inherited

accessor function for m_f1

Definition at line 110 of file Func1.cpp.

Func1 & func2 ( ) const

inherited

accessor function for m_f2

Definition at line 115 of file Func1.cpp.

int order ( ) const

virtualinherited

Return the order of the function, if it makes sense.

Reimplemented in Composite1, Ratio1, PlusConstant1, TimesConstant1, Product1, Diff1, and Sum1.
