The scope is as you would expect. The perhaps surprising thing is that the default value is only calculated once and reused, so each time you call the function you get the same list, not a new list initialized to []. The list is stored in f.__defaults__ (or f.func_defaults in Python 2.) def f(a, L=[]): … Read more
You want to get rid of those for loops. Try this: def exampleKernelA(M, x, N, y): “””Example kernel function A””” i, j = np.indices((N, M)) # Define the custom kernel function here kernel[i, j] = np.sqrt((x[i, 0] – y[j, 0]) ** 2 + (x[i, 1] – y[j, 1]) ** 2) return kernel You can also … Read more
You need to mark your assembly as COM visible by setting the COMVisibleAttribute to true (either at assembly level or at class level if you want to expose only a single type). Next you register it with: regasm /codebase MyAssembly.dll and finally call it from VBScript: dim myObj Set myObj = CreateObject(“MyNamespace.MyObject”)
The problem is here: int length_of_array(int some_list[]); Basically, whenever you pass an array as the argument of a function, no matter if you pass it like int arr[] or int arr[42], the array decays to a pointer (with ONE EXCEPTION, see below), so the signature above is equivalent to int length_of_array(int* some_list); So of course … Read more
Contrary to what others are saying, overloading by return type is possible and is done by some modern languages. The usual objection is that in code like int func(); string func(); int main() { func(); } you can’t tell which func() is being called. This can be resolved in a few ways: Have a predictable … Read more
Yes. You can use reflection. Something like this: Type thisType = this.GetType(); MethodInfo theMethod = thisType.GetMethod(TheCommandString); theMethod.Invoke(this, userParameters); With the above code, the method which is invoked must have access modifier public. If calling a non-public method, one needs to use the BindingFlags parameter, e.g. BindingFlags.NonPublic | BindingFlags.Instance: Type thisType = this.GetType(); MethodInfo theMethod = … Read more
