Functions

RISCV_DSP_ATTRIBUTE void riscv_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.

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

Parameters

• pInputRotations – [in] points to an array 3x3 rotation matrix (in row order)

• pOutputQuaternions – [out] points to an array quaternions

• nbQuaternions – [in] number of quaternions in the array
