Workspace Method xClip

Description

Clipping of the state vector.

The method allows you to apply hard limits the values of a
retrieval quantity. The retrieval quantity is specified by
``ijq``. All values of the quantity below ``limit_low``, are simply
set to ``limit_low``. And the same is performed with respect to
``limit_high``. That is, the data in x for the retrieval quantity
are forced to be inside the range [limit_low,limit_high].

Setting ijq=-1, is a shortcut for applying the limits on all
retrieval quantities.

Notice that limits must be specified in the unit used in x.
