matrixFirstDerivation

pyCGM2.Math.derivation.matrixFirstDerivation(motionList: List[Frame], sampleFrequency: int) → List[ndarray]

First-order derivation of the rotation matrix contained in a list of frames.

Parameters:

• motionList (List[Frame]) – List of Frame instances containing rotation matrices.

• sampleFrequency (int) – Sampling frequency of the data.

Returns:

List[np.ndarray] – List of first derivative matrices.
