Std.Arrays

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.
