Subject: merge revision(s) 19339: 	* lib/matrix.rb (Vector#eql?): typo of
 the method name as "eqn?". 	  (Vector#eqn?): removed. Defined by mistake. 
   Fixes [ruby-dev:36294]. Reported by weda <weda AT 	  issp.u-tokyo.ac.jp>
 and an anonymous user. 	* test/matrix/test_matrix.rb: added. 	*
 test/matrix/test_vector.rb: added.
