accumarray allows to aggregate items of an array in various ways, potentially applying some function to the items in the process. accumarray can be thought of as a lightweight reducer (see also: Introduction to MapReduce ). This topic will contain common scenarios where accumarray is especially use...

As you probably know if you came from OOP school, specializing an abstract class and use it is a practice you should keep in mind when writing your code. What if you could define an abstract function and specialize it in order to create different versions of it? Thinks it as a sort of function Inhe...

This section provides an overview of what azure-functions is, and why a developer might want to use it. It should also mention any large subjects within azure-functions, and link out to the related topics. Since the Documentation for azure-functions is new, you may need to create initial versio...

VHDL types can be unresolved or resolved. The bit type declared by the std.standard package, for instance, is unresolved while the std_logic type declared by the ieee.std_logic_1164 package is resolved. A signal which type is unresolved cannot be driven (assigned) by more than one VHDL process whil...

Functional programming decomposes a problem into a set of functions. Ideally, functions only take inputs and produce outputs, and don’t have any internal state that affects the output produced for a given input.below are functional techniques common to many languages: such as lambda, map, reduce. ...

Firebase launched its beta release of Cloud Functions for Firebase which is similar to using of Cloud Functions on Google Cloud Platform. Cloud Functions is a hosted, private, and scalable Node.js environment where you can run JavaScript code. Firebase SDK for Cloud Functions integrates the Firebas...

Haskell's function call syntax, explained with comparisons to C-style languages where applicable. This is aimed at people who are coming to Haskell from a background in C-style languages. In general, the rule for converting a C-style function call to Haskell, in any context (assignment, return...

ccapndave/elm-update-extra is a fantastic package which helps you handle more complex updating functions, and may be very useful.

In Java 8+, a functional interface is an interface that has just one abstract method (aside from the methods of Object). See JLS §9.8. Functional Interfaces.

The function is just like sub. But function returns a value. A function can accept single or multiple parameters.

Fitting a function which describes the expected occurence of data points to real data is often required in scientific applications. A possible optimizer for this task is curve_fit from scipy.optimize. In the following, an example of application of curve_fit is given.

Let's try to implement the basic higher orders functions like map and reduce using Elixir

We often need to run some code automatically during module install. This have many reasons for example configuring Sale module settings to meet our project requirements. In this topic you will learn how to make automated function run on module install.

The scope of this section is to explain the differences in theory and implementation for what happens with the parameters of a function upon calling. In detail the parameters can be seen as variables before the function call and inside the function, where the visible behaviour and accessibility to ...

You can create a custom loss function and metrics in Keras by defining a TensorFlow/Theano symbolic function that returns a scalar for each data-point and takes the following two arguments: tensor of true values, tensor of the corresponding predicted values. Note that the loss/metric (for display a...

As you already know, for the sake of immutability you can't process data using for loops and while loops. So we have recursive functions to rescue.

In Python function will be returned as soon as execution hits "return" statement.
