public struct Array2D<T>

Public Structure Array2D(Of T)

generic<typename T>
public value class Array2D

[<SealedAttribute>]
type Array2D<'T> =  struct end

Type Parameters

T

The element type of the array.

The Array2DT type exposes the following members.

	Name	Description
	Array2DT(Int32, Int32)	Constructs a new array.
	Array2DT(T, Int32, Int32)	Constructs a new array.
	Array2DT(Int32, Int32, Boolean)	Constructs a new array.

	Name	Description
	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 offset of the first element in the storage array.
	Values	Gets the storage array.

	Name	Description
	AsArray1D	Returns the array as an array with offset.
	AsArraySlice	Returns the array as an array slice with unit leadingDimension.
	Clear	Sets the specified number of elements to their default value.
	Clone	Creates a shallow copy of the 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.
	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 ValueTypeEquals(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 ValueTypeGetHashCode.)
	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.)
	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.
	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.
	VectorFrom	Returns an array slice with a specified stride that starts at the specified position.
	WithLeadingDimension	Returns the array at the current position with the specified leading dimension.

	Name	Description
	Equality	Checks whether two 2D arrays are equal.
	Inequality	Checks whether two 2D arrays are not equal.

	Name	Description
	Empty	Returns an empty 2D array.

Use the Array2DT 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.

Array2DT objects do not have a size. The actual dimensions must be supplied separately.

Caution
The Array2DT type is meant for performance-critical code. No bounds checks or other validation is performed.
