Namespaces
	GmVectorUtils
	Groups utilitary routines for working with vectors.

Typedefs
typedef arma::vec	GmVector
	The basic type for a GeMA vector object. Currently based on an Armadillo vector.

Functions
double	GmVectorUtils::sqrDistance (const GmVector &a, const GmVector &b)
	Returns the squared distance between vectors a and b.
double	GmVectorUtils::distance (const GmVector &a, const GmVector &b)
	Returns the distance between vectors a and b.
double	GmVectorUtils::sqrNorm (const GmVector &v)
	Returns the squared norm of vector v.
double	GmVectorUtils::equal (const GmVector &a, const GmVector &b, double relTol=GM_DOUBLECMP_RELTOL, double absTol=GM_DOUBLECMP_ABSTOL)
	Check to see if two vectors are equal comparing values using GmDoubleCmp::equal.
double	GmVectorUtils::isZero (const GmVector &a, double absTol)
	Check to see if a vector is zero using GmDoubleCmp::isZero over each component.
void	GmVectorUtils::setVectorMemory (GmVector &v, double *data, int nlin)
	Updates the memory area used internally by a vector. DANGEROUS. Should be used only by the bold ones who KNOWS what they are doing. More...
void	GmVectorUtils::resetVectorMemory (GmVector &v)
	Updates a vector that was prepared with setVectorMemory() to a common empty column vector. If the vector is already a common vector, resets it AND sets its memory pointer to NULL to become compatible with the checks by setVectorMemory()
bool	GmVectorUtils::hasSharedMemory (GmVector &v)
	Is this vector operating over a shared memory (set by setVectorMemory())?
void	GmVectorUtils::setVectorSize (GmVector &v, int nlin)
	Updates the logical vector size WITHOUT changin the used memory area. DANGEROUS. Should be used only by the bold ones who KNOWS what they are doing. More...
void	GmVectorUtils::print (const GmVector &v, const GmLogCategory &logger, GmLogLevel level, int fieldWidth, char format, int precision)
	Prints the vector using the specified logger, level and precision fields. Values are separated by spaces.
QString	GmVectorUtils::toString (const GmVector &v, int fieldWidth, char format, int precision, bool noBraces)
	Serializes the vector to a string using the specified precision fields. Coordinates are surrounded by [] (unless noBraces is true) and values separated by ', '.
void	GmVectorUtils::fillFromLuaTable (GmVector &v, LuaTable &t)
	Resizes and fills the vector v to receive the data stored in a lua table.
bool	GmVectorUtils::fillFromLuaTable (GmVector &v, LuaTable &t, int n)
	Resizes and fills the vector v to receive the data stored in a lua table. More...
