Memory2D<T> Structure

Represents a two-dimensional array stored in a memory block.

Definition

Namespace: Numerics.NET.Collections
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.1.5

public readonly struct Memory2D<T> : IStorage2D<T, MemorySlice<T>, Memory2D<T>>, 
	IStorage2D<T, Memory2D<T>>, IStorage2D<T>

Visual Basic

Public Structure Memory2D(Of T)
	Implements IStorage2D(Of T, MemorySlice(Of T), Memory2D(Of T)), 
	IStorage2D(Of T, Memory2D(Of T)), IStorage2D(Of T)

C++/CLI

generic<typename T>
public value class Memory2D : IStorage2D<T, MemorySlice<T>, Memory2D<T>>, 
	IStorage2D<T, Memory2D<T>>, IStorage2D<T>

[<SealedAttribute>]
type Memory2D<'T> = 
    struct
        inherit ValueType
        interface IStorage2D<'T, MemorySlice<'T>, Memory2D<'T>>
        interface IStorage2D<'T, Memory2D<'T>>
        interface IStorage2D<'T>
    end

Inheritance: Object → ValueType → Memory2D<T>

Implements: IStorage2D<T>, IStorage2D<T, Memory2D<T>>, IStorage2D<T, MemorySlice<T>, Memory2D<T>>

Type Parameters

T: The element type of the array.

Remarks

Use the Memory2D<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 block of memory. Columns are stored in contuguous blocks with a fixed number of elements between them.

Memory2D<T> objects do not have a size. The actual dimensions must be supplied separately.

Caution

The Memory2D<T> type is meant for performance-critical code. No bounds checks or other validation is performed.

Constructors

Memory2D<T>(Int32, Int32, Boolean)	Constructs a new array.
Memory2D<T>(Memory<T>, Int32, Int32)	Constructs a new array.

Properties

Item	Gets or sets the element at the specified position.
LeadingDimension	Gets the number of elements between the start of successive columns.
Offset	Gets the position of the first stored element in the array
Span2D	Gets a 2D span over the elements of the array. Return Value A Span2D<T>.

Methods

AsSlice	Returns the array as an array slice with unit leadingDimension.
Clear	Sets the specified number of elements to their default value.
Clone	Creates a deep copy of the array.
CloneData	Returns a new contiguous 2D array with the specified elements of the current array.
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.
Diagonal	Returns an array slice that corresponds to a column in the array.
Equals	Indicates whether this instance and a specified object are equal. (Overrides ValueType.Equals(Object))
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	Returns the hash code for this instance. (Overrides ValueType.GetHashCode())
GetIndex	Gets the index in the storage array of the element at the specified position.
GetType	Gets the Type of the current instance. (Inherited from Object)
Resize	Returns a new array with the specified size and leading dimension. Elements are copied to the new array.
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.
SliceFrom	Returns an array slice with a specified stride that starts at the specified position.
Span	Gets a span over the elements of the array. Return Value A Span<T>.
ToString	Returns the fully qualified type name of this instance. (Inherited from ValueType)
Transpose	Transposes the elements of the 2D array and returns the result.
TransposeTo	Transposes the elements of the 2D array and returns the result in the specified array.
WithLeadingDimension	Returns the array at the current position with the specified leading dimension.

Operators

Equality(Memory2D<T>, Memory2D<T>)	Checks whether two 2D arrays are equal.
Inequality(Memory2D<T>, Memory2D<T>)	Checks whether two 2D arrays are not equal.

Fields

Empty	Returns an empty 2D array.
Values	Gets the storage array.
