% Convert from device setting coordinates to
% sensor color space coordinates. Uses full
% basis function measurements in doing
% conversions so that it can compensate for
% device primary spectral shifts.
% 11/12/93 dhb Wrote it.
% 11/15/93 dhb Added deviceE output.
% 8/4/96 dhb Update for stuff bag routines.
% 8/21/97 dhb Update for structures.
% 3/10/98 dhb Change nBasesOut to nPrimaryBases.
% 4/5/02 dhb, ly Update for new calling interface.
% 11/22/09 dhb Check basis dimension and do the simple fast thing if it is 1.
% This will speed things up when there is no point in trying the
% fancier algorithm.
