-Signal Magnitude is the magnitude of a vector
+====== Signal Magnitude ======
- V = (x, y, z) is: |V| = √(x^2 + y^2 + z^2)
+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:
+<code>
+|V| = √(x^2 + y^2 + z^2).
+</code>

+The resulting signal will be a [[visual3d:documentation:visual3d_signal_types:derived_data_type|DERIVED]] signal and will be placed into the /RESULT_FOLDERS with /RESULT_NAME.
+==== Example ====
+The speed of the model's COG can be computed as the magnitude of its [[visual3d:documentation:pipeline:model_based_data_commands:model_cog_velocity|velocity signal]].
+<code>
+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
+;
+</code>
+The resulting signal will then be available as DERIVED::PROCESSED::COG_Velocity_Magnitude.
