If you never want the warning and consider it a shortcoming, use wnox, but if you only want to make one exception to it and want the warning to apply everywhere else, this is much more comprehensible. If you do not in fact have xi defined recursively in terms of xi, then unless z comes out undefined or as one of the infinities, then with the upper bound of the first integral being y, xi will be 0. This annotation is intended for the case where you think the warning is usually a good thing, but you dont want it to apply to a particular line thats doing something unusual.

For a complete list of operator symbols and the corresponding operator names, see. However, as the addition and subtraction operation is same for matrices and arrays, the operator is same for both cases. You can build expressions that use any combination of arithmetic, relational, and logical operators. If the original value was an unsigned integer of lesser width than int, it will be changed to a signed value as well usually this isnt that important, but it can have an effect, so its not a good idea to use unary.
