The Std.Arrays namespace contains the following items:
| Name | Description |
|---|---|
| All | Given an array and a predicate that is defined for the elements of the array, and checks if all elements of the array satisfy the predicate. |
| Any | Given an array and a predicate that is defined for the elements of the array, checks if at least one element of the array satisfies the predicate. |
| Chunks | Splits an array into multiple parts of equal length. |
| CircularlyShifted | Shift an array circularly left or right by a specific step size. |
| ColumnAt | Extracts a column from a matrix. |
| Count | Given an array and a predicate that is defined for the elements of the array, returns the number of elements an array that consists of those elements that satisfy the predicate. |
| Diagonal | Returns an array of diagonal elements of a 2-dimensional array |
| DrawMany | Repeats an operation for a given number of samples, collecting its outputs in an array. |
| Enumerated | Given an array, returns a new array containing elements of the original array along with the indices of each element. |
| Excluding | Returns an array containing the elements of another array, excluding elements at a given list of indices. |
| Filtered | Given an array and a predicate that is defined for the elements of the array, returns an array that consists of those elements that satisfy the predicate. |
| FlatMapped | Given an array and a function that maps an array element to some output array, returns the concatenated output arrays for each array element. |
| Flattened | Given an array of arrays, returns the concatenation of all arrays. |
| Fold | Iterates a function f through an array array, returning f(...f(f(initialState, array[0]), array[1]), ...). |
| ForEach | Given an array and an operation that is defined for the elements of the array, returns a new array that consists of the images of the original array under the operation. |
| Head | Returns the first element of the array. |
| HeadAndRest | Returns a tuple of first and all remaining elements of the array. |
| IndexOf | Returns the first index of the first element in an array that satisfies a given predicate. If no such element exists, returns -1. |
| IndexRange | Given an array, returns a range over the indices of that array, suitable for use in a for loop. |
| Interleaved | Interleaves two arrays of (almost) same size. |
| IsEmpty | Returns true if and only if an array is empty. |
| IsRectangularArray | Returns whether a 2-dimensional array has a rectangular shape |
| IsSorted | Given an array, returns whether that array is sorted as defined by a given comparison function. |
| IsSquareArray | Returns whether a 2-dimensional array has a square shape |
| Mapped | Given an array and a function that is defined for the elements of the array, returns a new array that consists of the images of the original array under the function. |
| MappedByIndex | Given an array and a function that is defined for the indexed elements of the array, returns a new array that consists of the images of the original array under the function. |
| MappedOverRange | Given a range and a function that takes an integer as input, returns a new array that consists of the images of the range values under the function. |
| Most | Creates an array that is equal to an input array except that the last array element is dropped. |
| MostAndTail | Returns a tuple of all but one and the last element of the array. |
| Padded | Returns an array padded at with specified values up to a specified length. |
| Partitioned | Splits an array into multiple parts. |
| Rest | Creates an array that is equal to an input array except that the first array element is dropped. |
| Reversed | Create an array that contains the same elements as an input array but in reversed order. |
| SequenceI | Get an array of integers in a given interval. |
| SequenceL | Get an array of integers in a given interval. |
| Sorted | Given an array, returns the elements of that array sorted by a given comparison function. |
| Subarray | Takes an array and a list of locations and produces a new array formed from the elements of the original array that match the given locations. |
| Swapped | Applies a swap of two elements in an array. |
| Tail | Returns the last element of the array. |
| Transposed | Returns the transpose of a matrix represented as an array of arrays. |
| Unzipped | Given an array of 2-tuples, returns a tuple of two arrays, each containing the elements of the tuples of the input array. |
| Where | Given a predicate and an array, returns the indices of that array where the predicate is true. |
| Windows | Returns all consecutive subarrays of length size. |
| Zipped | Given two arrays, returns a new array of pairs such that each pair contains an element from each original array. |
