Namespaces
	GmMatrixUtils
	Groups utilitary routines for working with matrices.

Typedefs
typedef arma::mat	GmMatrix
	The basic type for a GeMA matrix object. Currently based on an Armadillo matrix.

Functions
void	GmMatrixUtils::fill (GmMatrix &m, const double *data, int nlin, int ncol)
	Copy the contents of data to matrix m. If m size is different from nlin, ncol the matrix is resized. Assumes that data is layed out in COLUMN MAJOR FORMAT.

void	GmMatrixUtils::fillLine (GmMatrix &m, const double *data, int lin)
	Fills the specified line of a matrix m with the specified data.

void	GmMatrixUtils::fillColumn (GmMatrix &m, const double *data, int col)
	Fills the specified column of a matrix m with the specified data.

void	GmMatrixUtils::setMatrixMemory (GmMatrix &m, double *data, int nlin, int ncol)
	Updates the memory area used internally by a matrix. DANGEROUS. Should be used only by the bold ones who KNOWS what they are doing. More...

void	GmMatrixUtils::resetMatrixMemory (GmMatrix &m)
	Updates a matrix that was prepared with setMatrixMemory() to a common empty matrix. If the matrix is already a common matrix, resets it AND sets its memory pointer to NULL to become compatible with the checks by setMatrixMemory()

bool	GmMatrixUtils::hasSharedMemory (GmMatrix &m)
	Is this matrix operating over a shared memory (set by setMatrixMemory())?

void	GmMatrixUtils::setMatrixSize (GmMatrix &m, int nlin, int ncol)
	Updates the logical matrix size WITHOUT changin the used memory area. DANGEROUS. Should be used only by the bold ones who KNOWS what they are doing. More...

void	GmMatrixUtils::print (const GmMatrix &m, const GmLogCategory &logger, GmLogLevel level, int fieldWidth, char format, int precision)
	Prints the matrix using the specified logger, level and precision fields.

QString	GmMatrixUtils::toString (const GmMatrix &m, int fieldWidth, char format, int precision)
	Serializes the matrix to a string using the specified precision fields. Lines are surrounded by [] and values separated by ', '.

QString	GmMatrixUtils::toColMajorString (const GmMatrix &m, int fieldWidth, char format, int precision)
	Serializes the matrix to a "linear" string, using the specified precision fields, with values ordered in column major format. Values are separated by ', '.

void	GmMatrixUtils::fillFromLuaTable (GmMatrix &m, LuaTable &t)
	Resizes and fills the matrix m to receive the data stored in a lua table. More...

bool	GmMatrixUtils::fillFromLuaTable (GmMatrix &m, LuaTable &t, int nlin, int ncol)
	Resizes and fills the matrix m to receive the data stored in a lua table. More...

bool	GmMatrixUtils::updateFromLuaTable (GmMatrix &m, LuaTable &t)
	Updates the matrix m with the data stored in a lua table. The matrix size is left unchanged. More...
