The Signal_Magnitude command computes the vector magnitude of a multi-component signal for each frame of data. Concretely, given a 3-component vector V = (x, y, z) its magnitude is:

|V| = √(x^2 + y^2 + z^2).

Signal_Magnitude
! /SIGNAL_TYPES=
! /SIGNAL_FOLDER=ORIGINAL
! /SIGNAL_NAMES=
! /RESULT_FOLDERS=PROCESSED
! /RESULT_NAME=
! /APPLY_AS_SUFFIX_TO_SIGNAL_NAME=
;

The resulting signal will be a DERIVED signal and will be placed into the /RESULT_FOLDERS with /RESULT_NAME.

The speed of the model's COG can be computed as the magnitude of its velocity signal.

Signal_Magnitude
/SIGNAL_TYPES=LINK_MODEL_BASED
/SIGNAL_FOLDER=ORIGINAL
/SIGNAL_NAMES=COG_Velocity
! /RESULT_FOLDERS=PROCESSED
/RESULT_NAME=_Magnitude
/APPLY_AS_SUFFIX_TO_SIGNAL_NAME=TRUE
;

The resulting signal will then be available as DERIVED::PROCESSED::COG_Velocity_Magnitude.
