NativeArray2D<T> Structure

Represents a 2-dimensional array stored in a linear array.

Definition

Namespace: Extreme.Collections
Assembly: Extreme.Numerics (in Extreme.Numerics.dll) Version: 8.1.23
C# 
public struct NativeArray2D<T>
Inheritance
Object  →  ValueType  →  NativeArray2D<T>

Type Parameters

T
The element type of the array.

Remarks

Use the NativeArray2D<T> structure to represent two-dimensional arrays in a format suitable for calling external libraries like BLAS and LAPACK. The two-dimensional array is stored in a linear array. Columns are stored in contuguous blocks with a fixed number of elements between them.

NativeArray2D<T> objects do not have a size. The actual dimensions must be supplied separately.

  Caution

The NativeArray2D<T> type is meant for performance-critical code. No bounds checks or other validation is performed.

Constructors

NativeArray2D<T> Constructs a new array.

Properties

LeadingDimension Gets the number of elements between the start of successive columns.
Offset Gets the offset of the first element in the storage array.
Values Gets the storage array.

Methods

AsArray1D Returns the array as an array with offset.
AsArraySlice Returns the array as an array slice with unit leadingDimension.
Column Returns an array with offset that corresponds to a column in the array.
ColumnFrom Returns an array with offset that corresponds to a column in the array that starts at the specified position.
CreateEmpty Creates an empty 2D array with the specified leading dimension.
Diagonal Returns an array slice that corresponds to a column in the array.
Equals Checks if an object is equal to this instance.
(Overrides ValueType.Equals(Object))
From(Int32) Returns the array starting at the specified position on the main diagonal.
From(Int32, Int32) Returns the array starting at the specified position.
From(Int32, Int32, Int32) Returns the array starting at the specified position with the specified leading dimension.
GetHashCode Gets a hash code for this instance.
(Overrides ValueType.GetHashCode())
GetIndex Gets the index in the storage array of the element at the specified position.
GetTypeGets the Type of the current instance.
(Inherited from Object)
Row Returns the array slice that corresponds to a row in the array.
RowFrom Returns the array slice that corresponds to a row in the array that starts at the specified position.
ToStringReturns the fully qualified type name of this instance.
(Inherited from ValueType)
VectorFrom Returns an array slice with a specified stride that starts at the specified position.

Operators

Equality(NativeArray2D<T>, NativeArray2D<T>) Checks whether two 2D arrays are equal.
Inequality(NativeArray2D<T>, NativeArray2D<T>) Checks whether two 2D arrays are not equal.

Fields

Empty Returns an empty 2D array.
