Description

Conversions from rotation to quaternion.

Function Documentation

arm_rotation2quaternion_f32()

void arm_rotation2quaternion_f32	(	const float32_t *	pInputRotations,
		float32_t *	pOutputQuaternions,
		uint32_t	nbQuaternions
	)

Conversion of a rotation matrix to an equivalent quaternion.

Conversion of a rotation matrix to equivalent quaternion.

Parameters

[in]	pInputRotations	points to an array 3x3 rotation matrix (in row order)
[out]	pOutputQuaternions	points to an array quaternions
[in]	nbQuaternions	number of quaternions in the array

q and -q are representing the same rotation. This ambiguity must be taken into account when using the output of this function.
