Inheritance: Object → ValueType → ArrayAttributes

Remarks

Use the ArrayAttributes structure to represent information about the shape, transformation and mutability of a vector or matrix.

Properties

CheckForMissingValues	Gets whether checks for missing values should be made.
CopyOnWrite	Gets whether copy-on-write semantics are enabled.
HasStructuralZeros	Indicates whether the matrix has elements that must be zero.
HasSymmetry	Indicates whether the matrix is symmetric or Hermitian.
IsConjugated	Indicates that the elements of the array are conjugated.
IsConjugateTransposed	Indicates that the array is transposed and its elements conjugated.
IsDiagonal	Indicates that only the elements on the diagonal are stored.
IsFull	Indicates that the full matrix is stored.
IsHermitian	Indicates whether the matrix is Hermitian.
IsMissingValueAware	Gets whether operations on the array take into account missing values.
IsReadOnly	Gets whether the elements of the array are read-only.
IsStoredInLowerTriangle	For triangluar, symmetric and Hermitian matrices, indicates that only the elements in the lower triangle are stored.
IsStoredInUpperTriangle	For triangluar, symmetric and Hermitian matrices, indicates that only the elements in the upper triangle are stored.
IsSymmetric	Indicates whether the matrix is symmetric.
IsTransposed	Indicates that the matrix is transposed.
IsUnitDiagonal	Indicates whether the diagonal elements of a triangular matrix are all equal to one.
MatrixDiagonal	Indicates whether the diagonal of a triangular matrix contains all ones.
Mutability	Gets the mutability of the array.
StoredTriangle	For triangular matrices and matrices with symmetry, indicates whether only the elements in the upper or lower triangle are stored.
Structure	Gets the matrix structure of the array.
SymmetryOperation	Gets the operation under which the matrix has symmetry.
TransposeOperation	Gets how the stored data is transformed.

Methods

Conjugate	Returns array attributes of the array if it were transposed.
ConjugateTranspose	Returns array attributes of the array if i t were transposed and its elements were conjugated.
DefaultForIntent	Returns the default array attributes for an array that is created with the specified intent.
Equals	Indicates whether this instance and a specified object are equal. (Overrides ValueType.Equals(Object))
GetHashCode	Returns the hash code for this instance. (Overrides ValueType.GetHashCode())
GetType	Gets the Type of the current instance. (Inherited from Object)
ToString	Returns the fully qualified type name of this instance. (Inherited from ValueType)
Transpose	Returns array attributes of the array if it were transposed.

Operators

BitwiseAnd(ArrayAttributes, ArrayAttributes)	Returns the array attribute flags that are set in two array attributes.
BitwiseOr(ArrayAttributes, ArrayAttributes)	Returns the array attribute flags that are set in either of two array attributes.
Equality(ArrayAttributes, ArrayAttributes)	Compares two array attribute values for equality.
Implicit(Int32 to ArrayAttributes)	Converts an integer to array attributes.
Inequality(ArrayAttributes, ArrayAttributes)	Compares two array attribute values for inequality.
OnesComplement(ArrayAttributes)	Returns the complement of the attribute flags.

Fields

Conjugated	Specifies that the array's elements are conjugated.
ConjugateTransposed	Specifies that the array is transposed and its elements conjugated.
Default	Gets the default array attributes for a vector or matrix.
DefaultMutable	Gets the default array attributes for a vector or matrix.
Diagonal	Specifies that the matrix is a diagonal matrix and all off-diagonal elements are zero.
Full	Specifies that all elements of a matrix can take on any value.
Hermitian	Specifies that the matrix is Hermitian. This implies that the matrix is square.
LowerTriangular	Specifies that the matrix is lower triangular and all elements above the main diagonal are zero.
None	Empty array attributes.
NonUnitDiagonal	Specifies that the diagonal elements of a triangular matrix can take on any value.
ReadOnlyDefault	Gets the default array attributes for a read-only vector or matrix.
StoredInLowerTriangle	Specifies that the matrix elements of a triangular, symmetric, or Hermitian matrix are stored in the lower triangular part of the matrix.
StoredInUpperTriangle	Specifies that the matrix elements of a triangular, symmetric, or Hermitian matrix are stored in the upper triangular part of the matrix.
Symmetric	Specifies that the matrix is symmetric. This implies that the matrix is square.
TransformMask	Mask for flags that indicate if an array is transposed and/or conjugated.
Transposed	Specifies that the array is transposed.
UnitDiagonal	Specifies that the diagonal elements of a triangular matrix have the fixed value of 1.
UpperTriangular	Specifies that the matrix is upper triangular and all elements below the main diagonal are zero.
