i have made a function in Prolog:- mean(L, M) :- sum(L, S), length(L, N), M is S/N. sum([],0). sum([H|T],Y):-
I\'m trying to find an efficient, numerically stable algorithm to calculate a rolling variance (for instance, a variance over a 20-period rolling window). I\'m aware of the Welford algorithm that effi
@Jerry Coffin I get the logic, while(File>>value)//while input just taken from file is true .... do computation.
The C# spec states that an argument type cannot be both covariant and contravariant at the same time.
I\'m having a little problem understanding variance of methods when overloading. While this perfectly works due to covariance in the return type
The source data : static double[] felix = new double[] { 0.003027523, 0.002012256, -0.001369238, -0.001737660, -0.001647287,
Suppose I want to add functionality like map to a Scala List, something along the lines of list mapmap f, which applies the function f to each element of list twice. (A more serious example might be i
What does the statement mean? From here ref and out parameters in C# and cannot be marked as variant. 1) Does it mean that the following can not be done.
Is there a way to refl开发者_Python百科ect on an interface to detect variance on its generic type parameters and return types? In other words, can I use reflection to differentiate between the two int
@uncheckedVariance can be used to bridge the gap between Scala\'s declaration site variance annotations and Java\'s invariant generics.
