Namespaces
namespace	GmVectorUtils
	Groups utilitary routines for working with vectors.

Functions
double	GmVectorUtils::sqrNorm (const double *v, unsigned s)
	Returns the squared norm of vector v, with size s.
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.
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.
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.
