%MATSAVE  Create and save structure of variables as mat-file. 
%
%   MATSAVE NAME X1 X2 ... XN  where X1 ... XN are names of 
%   variables in the current workspace, first creates a structure
%
%       NAME.X1, NAME.X2, NAME.X3
%
%   then saves it as a .mat file called NAME, and finally loads this 
%   mat-file into the current workspace.
%
%   The mat-file is save at the location specified in JLAB_SETTINGS
%   by the value of DIRNAMES.MATFILES.  If this variable is not
%   found, it the mat-file is save to the JLAB directory.
%
%   By default NAME is a string rather than a variable.  However,
%   NAME can also be a variable whose value is a string, though
%   the use of the '-n' flag.  Then
%
%        MATSAVE -N VAR X1 ... XN
%
%   with VAR='sample' will create a structure named 'sample'.
%
%   The version of mat-file format to save in may also be specified 
%   through the of the -v flag, such that
%
%        MATSAVE -V6 NAME X1 ... XN
%
%   will create a structure NAME and save it as a Version 6 mat-file;
%   see SAVE for allowable version options.
%
%   See also MAKE, USE.
%
%   Usage:  matsave name x1 x2 x3
%           matsave -n var x1 x2 x3
%           matsave -v6 -n var x1 x2 x3
