Constructor & Destructor Documentation

template<class TYPE>
RDNumeric::Matrix< TYPE >::Matrix ( unsigned int  nRows,
unsigned int  nCols 
) [inline]

Initialize with a size.

Definition at line 33 of file Matrix.h.

template<class TYPE>
RDNumeric::Matrix< TYPE >::Matrix ( unsigned int  nRows,
unsigned int  nCols,
TYPE  val 
) [inline]

Initialize with a size and default value.

Definition at line 41 of file Matrix.h.

template<class TYPE>
