Constructor & Destructor Documentation

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

Initialize with a size.

Definition at line 28 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 36 of file Matrix.h.

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

Initialize from a pointer.

NOTE: this does not take ownership of the data, if you delete the data externally, this Matrix will be sad.

copy constructor

We make a copy of the other vector's data.
