function appsave(ffffnnnn,vvvvnnnn,vvvvaaaa)
%APPSAVE appends a variable to an existing MAT-file.
%	APPSAVE('FILENAME', 'VARNAME', VAR) appends the variable
%	to FILENAME.mat and assigns the variable name 'VARNAME'.
%
%	The actual file is a MEX-file. See appsave.c for details.
%	There is also a MEX-file available, which accelerates
%	the processing speed.
