Classes
class	CH_Matrix_Classes::Memarray
	A simple memory manager for frequent allocation and deallocation of arrays of roughly the same size. More...
class	CH_Matrix_Classes::Memarrayuser
	All derived classes share a common Memarray memory manager, which is generated with the first user and destructed when the last user is destructed. More...

Functions
template<class T >
int	CH_Matrix_Classes::mem_provide (Memarray &memarray, long provide, long in_use, long &avail, T *&store)
	provide sufficient memory for an existing array, reallocating and copying the old information upon need, returns 0 upon success, !=0 upon failure. More...
template<class T >
int	CH_Matrix_Classes::mem_provide_init0 (Memarray &memarray, long provide, long &avail, T *&store)
	provide sufficient memory for an existing array, reallocating and copying the old information and initializing the new entries to 0, returns 0 upon success, !=0 upon failure. More...

mem_provide()

template<class T >

int CH_Matrix_Classes::mem_provide ( Memarray &  memarray, long  provide, long  in_use, long &  avail, T *&  store  )

inline

provide sufficient memory for an existing array, reallocating and copying the old information upon need, returns 0 upon success, !=0 upon failure.

Parameters

memarray	the Memory Manger which provided the address in store
provide	the minimum number of entries needed
in_use	the number of entries currently in use
avail	the number of entries currently available and available afterwards
store	the current address and the ouput address of the starting element
