Workspace Method iyReplaceFromAux

Description

Change of main output variable.

With this method you can replace the content of iy with one of
the auxiliary variables. The selected variable (by *aux_var*) must
be part of iy_aux_vars. The corresponding data from iy_aux are
copied to form a new iy (iy_aux is left unchanged). Elements of
iy correponding to Stokes elements not covered by the auxiliary
variable are just set to zero.

Jacobian variables are not handled.
