Constructor & Destructor Documentation

template<typename T >
Sacado::Fad::MemPoolStorage< T >::MemPoolStorage ( const int  sz,

inline
template<typename T >
void Sacado::Fad::MemPoolStorage< T >::resizeAndZero ( int  sz)

Resize the derivative array to sz.

This method doest not preserve any existing derivative components but sets any that are added to zero.
