I have an array with a long calculation as index and want to add 1*(the imaginary unit) to that element in the array and I would like to do that without writing it twice, how do I do that?

There's nothing equivalent to the operator += in matlab. There is no way round to writing the variable name twice, I'm afraid.

You can us something like this so that you don't have to do the very long index computation twice
ind = % very long computation here
array(ind) = array(ind) + sqrt(-1);
