Открытые методы

Метод Описание
getPoints ( $source, array $args = [] ) : array Determine where the input $source argument is a callback function, a set of arrays, or neither. If $source is a callback function, run it through the functionToPoints() method with the input $args, and set $points to output array. If $source is a set of arrays, simply set $points to $source. If $source is neither, throw an Exception.
validate ( array $points, number $degree = 2 ) : boolean Validate that there are enough input arrays (points), that each point array has precisely two numbers, and that no two points share the same first number (x-component)

Защищенные методы

Метод Описание
functionToPoints ( callable $function, number $start, number $end, number $n ) : array Evaluate our callback function at n evenly spaced points on the interval between start and end
sort ( array $points ) : array Sorts our coordinates (arrays) by their x-component (first number) such that consecutive coordinates have an increasing x-component.

Описание методов

functionToPoints() защищенный статический Метод

Evaluate our callback function at n evenly spaced points on the interval between start and end
protected static functionToPoints ( callable $function, number $start, number $end, number $n ) : array
$function callable f(x) callback function
$start number the start of the interval
$end number the end of the interval
$n number the number of function evaluations
Результат array

getPoints() публичный статический Метод

Determine where the input $source argument is a callback function, a set of arrays, or neither. If $source is a callback function, run it through the functionToPoints() method with the input $args, and set $points to output array. If $source is a set of arrays, simply set $points to $source. If $source is neither, throw an Exception.
public static getPoints ( $source, array $args = [] ) : array
$source The source of our approximation. Should be either a callback function or a set of arrays.
$args array The arguments of our callback function: start, end, and n. Example: [0, 8, 5]. If $source is a set of arrays, $args will default to [].
Результат array

sort() защищенный статический Метод

Sorts our coordinates (arrays) by their x-component (first number) such that consecutive coordinates have an increasing x-component.
protected static sort ( array $points ) : array
$points array
Результат array

validate() публичный статический Метод

Validate that there are enough input arrays (points), that each point array has precisely two numbers, and that no two points share the same first number (x-component)
public static validate ( array $points, number $degree = 2 ) : boolean
$points array Array of arrays (points)
$degree number The miminum number of input arrays
Результат boolean
