function theResult = psset(self, theField, theValue)

% ps/psset -- Set a "ps" field value.
%  psset(self, 'theField', thevalue) sets the value
%   of 'theField' associated with self, a "ps" object,
%   to theValue.  If the field is the name of a graphics
%   associated with the handle of self, that property is
%   set.
%  psset(self, 'theField') returns the value of the field.
%  psset(self) returns all the current "ps" fields in a 
%   "struct".
