from_T2

Return orientation object R from transformation matrix T and its derivative der(T)

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Syntax

R = Frames.from_T2(T, der_T);

Description

Computes the orientation object from a transformation matrix T and the derivative der(T) of the transformation matrix. Usually, it is more efficient to use function "from_T" instead, where the angular velocity has to be given as input argument. Only if this is not possible or too difficult to compute, use function from_T2(…).
