问题 I'm doing a simple normalization on a vector (weights), trying to make use of STL algorithms to make the code as clean as possible (I realize this is pretty trivial with for loops): float tot = std::accumulate(weights.begin(), weights.end(), 0.0); std::transform(weights.begin(), weights.end(), [](float x)->float{return(x/tot);}); At present, tot is not visible to the anonymous function, so this doesn't compile. What's the best way of making a local variable visible to the anonymous function?

问题 I'm looking into launch coroutine builder which takes coroutine code as block: suspend CoroutineScope.() -> Unit . We usually pass the code as lambda. However, I was wondering how to pass this function as explicit parameter to launch function. coroutineScope { launch(block = ::myFunction) } suspend fun CoroutineScope.myFunction(): Unit { // coroutine code } It gives following error Type mismatch. Required: suspend CoroutineScope.() → Unit Found: KSuspendFunction0<Unit> What is it that i'm

问题 In MATLAB I am trying to do a function on a cell array, but am not having much luck. I would like to create a cellfun which checks whether str2double returns NaN values and then perform the str2double on the values which aren't NaNs . I'm trying to use an anonymous function with an IF Else sort of statement in it but not really getting anywhere. Here is what I have come up with so far: x = cellfun(@(x)~isnan(str2double(x)),str2double(x)) However it doesn't work, could anybody help me out? 回答1
