But in mechanics and, more generally, in physics, this concept is frequently understood as a coordinate transformation ( importantly, a transformation of an orthonormal basis ), because for any motion of a body there is an inverse transformation which if applied to the frame of reference results in the body being at the same coordinates.

A CCR document can generally be converted into CCD using Extensible Stylesheet Language Transformations ( XSLT ), but it is not always possible to perform the inverse transformation, since some CCD features are not supported in CCR . HITSP provides reference information that demonstrates how CCD and CCR ( as HITSP C32 ) are embedded in CDA.

Transformation of Van?ek's LSSA is possible, as is most easily seen by writing the forward transform as a matrix; the matrix inverse ( when the matrix is not singular ) or pseudo-inverse will then be an inverse transformation; the inverse will exactly match the original data if the chosen sinusoids are mutually independent at the sample points and their number is equal to the number of data points.
