% DESCRIPTION: SETCOV Set the property 'cov'
%
% CALL:        obj = obj.setCov([1:12]);
%              obj = obj.setCov(plist('cov', [1:12]));
%              obj.setCov([1:12]);
%
% INPUTS:      obj - can be a vector, matrix, list, or a mix of them.
%              pl  - to set the 'cov' with a plist specify only one plist with
%                    only one key-word 'cov'.
