Namespaces
	mrpt
	This is the global namespace for all Mobile Robot Programming Toolkit (MRPT) libraries.

	mrpt::math
	This base provides a set of functions for maths stuff.

	mrpt::math::jacobians
	A collection of functions to compute jacobians of diverse transformations, etc (some functions are redirections to existing methods elsewhere, so this namespace is actually used with grouping purposes).

Functions
void	mrpt::math::jacobians::jacob_quat_from_yawpitchroll (mrpt::math::CMatrixFixedNumeric< double, 4, 3 > &out_dq_dr, const double yaw, const double pitch, const double roll)
