To document a function, it is often helpful to have an example script which uses your function. The publish function in Matlab can then be used to generate a help file with embedded pictures, code, links, etc. The syntax for documenting your code can be found here.
The Function
This function uses ...
type Person = {
Age : int
PassedDriversTest : bool }
let someone = { Age = 19; PassedDriversTest = true }
match someone.PassedDriversTest with
| true when someone.Age >= 16 -> printfn "congrats"
| true -> printfn "wait until you are 16"
| false -> p...
compile built-in function can be used to precompile an expression to a code object; this code object can then be passed to eval. This will speed up the repeated executions of the evaluated code. The 3rd parameter to compile needs to be the string 'eval'.
>>> code = compile('a * b + c', '&l...
>>> variables = {'a': 6, 'b': 7}
>>> eval('a * b', globals=variables)
42
As a plus, with this the code cannot accidentally refer to the names defined outside:
>>> eval('variables')
{'a': 6, 'b': 7}
>>> eval('variables', globals=variables)

You can fetch the current properties of the Annotation by using Reflection to fetch the Method or Field or Class which has an Annotation applied to it, and then fetching the desired properties.
@Retention(RetentionPolicy.RUNTIME)
@interface MyAnnotation {
String key() default "foo";...
The Application directive defines application-specific attributes. It is provided at the top of the global.aspx file.
The basic syntax of Application directive is:
<%@ Application Language="C#" %>
The attributes of the Application directive are:

You can also use regular expressions to split a string. For example,
import re
data = re.split(r'\s+', 'James 94 Samantha 417 Scarlett 74')
print( data )
# Output: ['James', '94', 'Samantha', '417', 'Scarlett', '74']
If you have a vsix file, you can install it by running the file.

int x = 5 / 0; // Undefined behavior
Division by 0 is mathematically undefined, and as such it makes sense that this is undefined behavior.
However:
float x = 5.0f / 0.0f; // x is +infinity
Most implementation implement IEEE-754, which defines floating point division by zero to return N...
Category theory is a modern mathematical theory and a branch of abstract algebra focused on the nature of connectedness and relation. It is useful for giving solid foundations and common language to many highly reusable programming abstractions. Haskell uses Category theory as inspiration for some o...
A category C consists of:
A collection of objects called Obj(C) ;
A collection (called Hom(C)) of morphisms between those objects. If a and b are in Obj(C), then a morphism f in Hom(C) is typically denoted f : a -> b, and the collection of all morphism between a and b is denoted hom(a,b) ;
A...
First of all, you cannot "install" Java EE. Java EE consists of a number of specifications.
You can install implementations of those specifications however.
Depending on your needs, there are lots of possibilities.
To install most (or all) of the specifications, you can choose a Java EE...
This will give current system version.
Objective-C
NSString *version = [[UIDevice currentDevice] systemVersion]
Swift
let version = UIDevice.currentDevice().systemVersion
Swift 3
let version = UIDevice.current.systemVersion
You can choose between major distributions of LaTeX:
TeX Live (Windows, Linux, and OS X), the standard, cross-platform distribution.
MacTeX (Mac) A packaged version of TeX Live made for OS X with some Mac-specific tools
MiKTeX (Windows) A separate distribution entirely that

Detailed instructions on getting WSO2 set up or installed.
Almost all the WSO2 Products can be started using the wso2server.sh/bat files that can be found in the <Product_Home>/bin folder of each product. When you run the sh/bat script it will star the particular WSO2 product with default set...
The use of null values is strongly discouraged, unless interacting with legacy Java code that expects null. Instead, Option should be used when the result of a function might either be something (Some) or nothing (None).
A try-catch block is more appropriate for error-handling, but if the function ...
