Hello, I'm quite new to numpy, trying to migrate from IDL. I'm not able to find any 'shift' function in numpy, i.e. a function that shifts the content of an array by a certain number of elements. a = [1,2,3,4,5,6] shift(a,2) = [3,4,5,6,1,2] In IDL this works even on multidemiensional arrays, b=shift(a,4,7,5) shifts by 4 in the first, 7 in the second and 5 in the third component. Is there some similar module existing? Thanks & best regards, Andreas ------------------------------------------------------------------- Andreas Reigber Institut fuer Hochfrequenztechnik DLR - Oberpfaffenhofen Tel. : ++49-8153-282367 Postfach 1116 eMail: Andreas.Reigber@dlr.de D-82230 Wessling -------------------------------------------------------------------
