You can use 'from' and 'goto' blocks from simulink-->signal routing library.

a1=a+b( for a1(tag name) use goto block to store the value(either 'local' or global), then do continuously..

Hey, in your case you don't have an algebrical loop because your operations are in ''cascade'' (english translation of a french word, I don't know if it's understandable). If you want to create one, you have to make an operation like a1 = a + a1.
