In some cases we need to apply functions to a set of ND-arrays. Let's look at this simple example.
A(:,:,1) = [1 2; 4 5];
A(:,:,2) = [11 22; 44 55];
B(:,:,1) = [7 8; 1 2];
B(:,:,2) = [77 88; 11 22];
A =
ans(:,:,1) =
1 2
4 5
ans(:,:,2) =
11 22

By default, Shapes in Excel do not have a specific way to handle single vs. double clicks, containing only the "OnAction" property to allow you to handle clicks. However, there may be instances where your code requires you to act differently (or exclusively) on a double click. The follow...

If we want to get the x-cordinate of origin of the view, then we need to write like:
view.frame.origin.x
For width, we need to write:
view.frame.size.width
But if we add a simple extension to an UIView, we can get all the attributes very simply, like:
view.x
view.y
view.width
view.height...
Some ADO.NET providers (most notably: OleDB) do not support named parameters; parameters are instead specified only by position, with the ? place-holder. Dapper would not know what member to use for these, so dapper allows an alternative syntax, ?foo?; this would be the same as @foo or :foo in other...
One of Angular's strength's is client-side form validation.
Dealing with traditional form inputs and having to use interrogative jQuery-style processing can be time-consuming and finicky. Angular allows you to produce professional interactive forms relatively easily.
The ng-model directive provide...
Imagine that we have a class Math.php with logic of calculating of fiobanacci and factorial numbers. Something like this:
<?php
class Math {
public function fibonacci($n) {
if (is_int($n) && $n > 0) {
$elements = array();
$elements[1] = 1;

Here are examples of how to use monotonic predicates instead of impure, non-monotonic constructs in your programs:
dif/2 is meant to be used instead of non-monotonic constructs like (\=)/2
arithmetic constraints (CLP(FD), CLP(Q) and others) are meant to be used instead of moded arithmetic predi...

Search for all facts involving a pattern in an hypothesis or conclusion:
Coq < Search (_ + O).
plus_n_O: forall n : nat, n = n + 0
The _ character serves as a wildcard, it can be used multiple times:
Coq < Search (S _ <= _).
le_S_n: forall n m : nat, S n <= S m -> n <= m

Using the document-ready event can have small performance drawbacks, with delayed execution of up to ~300ms. Sometimes the same behavior can be achieved by execution of code just before the closing </body> tag:
