i trying write program takes in list of numbers , adds 1 each element in list. if list 0 return nil. tried doing recursively shows me no output. know it's simple beginner , hard me think problem recursively. thanks! a list made of cons . has first value , list consisting of rest of list except first value. should check if list null (or endp same) , if isn't make cons calculation have first , recursive call using rest . argument. (add-1 '(1 . (2 . (3 . ())))) ; ==> (2 . (3 . (4 . ()))) or more commonly written: (add-1 '(1 2 3)) ; ==> (2 3 4)

i found code using datagramchannel.write() . code asked host ip , port before connected , allow sending (via datagramchannel.write() ). being new network programming, seemed odd wouldn't request destination ip/port. why not? oracle's documentation states this method may invoked if channel's socket connected, in case sends datagrams directly socket's peer. what mean "the socket's peer"? datagramchannel part of java.nio package. take parameter bytebuffer send connected channel. before trying send should connect using inetsocketaddress, takes host ip , port parameter. connect(socketaddress remote) --> connects channel underlying socket. can socket datagramchannel because channel non blocking io used read/write purpose. socket peer's nothing remote machine.

i'm trying populate dimension tables on regular basis , i've thought of 2 ways of getting distinct values dimension: using aggregate transformation , using "group by" operation. using sort transformation while removing duplicates. i'm not sure 1 better (more efficient), or 1 adopted more in industry. i tried perform tests using dummy data, can't quite solid answer. p.s. using select distinct source not option here. my first choice correct in source query if possible. realise isn't option, sake of completeness future readers: first check whether had problem in source query creating duplicates. whenever distinct seems necessary, first see whether there's problem query needs resolving. my second choice distinct - if possible - because 1 of cases quicker resolve in sql in ssis; realise that's not option you. from point, you're getting situation might need try out remaining options. aside using aggregate or sort in ssi...

"reference non-existent field 'sp'." if try "exist name" function works variables not handles so: handle.a=figure; exist handle.a; returns 0 while handle.a=figure; a=handle.a; exist returns 1 but i'm looking for: handle.a=figure; exist handle.a ans=1 %without setting handle: exist handle.a ans=0 i hope post understandable. thank help! klaus let me rephrase: assigning handle field of structure. want test whether there valid handle in field, , guard against wrong: (1) there's no field, (2) it's empty, (3) it's array instead of scalar, (4) it's not handle, (5) it's not valid handle. thus: tf = isfield(handle,'a') && isscalar(handle.a) && ishandl...
