DECLARE_REF_MATRIX

#define DECLARE_REF_MATRIX	(		x,
			ptr,
			lin,
			col
	)		GmMatrix x((ptr), (lin), (col), false, true)

An auxiliary macro to help correctly define a matrix that binds itself to a memory area with data already initialized and interpreted in COLUMN MAJOR FORMAT.

This is a very fast option, that doesn't allocate any extra memory and is very usefull to use matrix operations over a previous allocated area.

This matrix cannot be resized in any way. The memory referenced by the matrix should be available through the entire lifetime of the matrix.

IMPORTANT: Any COPY of this matrix will make a COPY of the data and won't point to the original memory area anymore.

GM_MATRIX_DEFINED

#define GM_MATRIX_DEFINED

We are going to use an Armadillo matrix as our base matrix interface.

The typedef GmMatrix is used to make life a little bit easier if we ever wish to exchange our base linear algebra package.
