Subject:      circular shift a matrix in SAS/IML
Comments: To: sas-l@uga.edu

Is it possible to circular shift a matrix in SAS/IML?
I mean:

   a = { -1 -2 , -3 0 , 1 2 };
   c=CIRCSHIFTROW(a,1);


   c = { -3 0 , 1 2 ,  -1 -2};

or
   c=CIRCSHIFTCOLUMN(a,1);


   c = { -2 -1 , 0 -3 , 2 1 };

Thanks
