MathWorks.MATLAB.NET.Arrays.MWArray Class

Namespace: MathWorks.MATLAB.NET.Arrays

Encapsulate native MATLAB mxArray

Description

MWArray is an abstract C# class that serves as the root of the MATLAB^® array class hierarchy. Its derived classes implement MATLAB data types. It encapsulates a native MATLAB mxArray and provides a managed API for accessing, formatting, and manipulating the native array.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

Public Properties

`ArrayType` — Derived type of `MWArray`
`MWArrayType`

This property is read-only.

Syntax

public MWArrayType ArrayType { get; }

The derived type of the array, specified as an MWArrayType object.

`Dimensions` — Return native integer array containing size of each dimension of `MWArray`
positive integer

This property is read-only.

Syntax

public virtual int[] Dimensions { get; }

See size.

`IsCellArray` — Flag indicating if `MWArray` is `MWCellArray`
`boolean`

This property is read-only.

Syntax

public bool IsCellArray { get; }

See iscell.

`IsCharArray` — Flag indicating if `MWArray` is `MWCharArray`
`boolean`

This property is read-only.

Syntax

public bool IsCharArray { get; }

See ischar.

`IsDisposed` — Handle status of encapsulated `MWArray`
`boolean`

This property is read-only.

Syntax

public virtual bool IsDisposed { get; }

`IsEmpty` — Flag indicating if `MWArray` is empty
`boolean`

This property is read-only.

Syntax

public virtual bool IsEmpty { get; }

See isempty.

`IsLogicalArray` — Flag indicating if `MWArray` is `MWLogicalArray`
`boolean`

This property is read-only.

Syntax

public bool IsLogicalArray { get; }

See islogical.

`IsNumericArray` — Flag indicating if `MWArray` is `MWNumericArray`
`boolean`

This property is read-only.

Syntax

public bool IsNumericArray { get; }

See isnumeric.

`IsStringArray` — Flag indicating if `MWArray` is `MWStringArray`
`boolean`

This property is read-only.

Syntax

public bool IsStringArray { get; }

See isstring.

`IsStructArray` — Flag indicating if `MWArray` is `MWStructArray`
`boolean`

This property is read-only.

Syntax

public bool IsStructArray { get; }

See isstruct.

`Item` — Generic MATLAB indexer returning result as `MWArray`
`MWArray`

Syntax

public MWArray this[
	params int[] indices
] { get; set; }

An index can be any number of integers corresponding to the array's dimensions. As with MATLAB, a single index will return the nth element in the array. NOTE: The generic array indexer supports numeric, logical, char, and cell array types. For complex numeric arrays, both the real and the imaginary components are returned.

Array indexing in this API, as in MATLAB, is one-based rather than zero-based.

`NativeGCBlockSize` — Unmanaged memory block size in bytes
positive integer

This property is read-only.

Syntax

public static long NativeGCBlockSize { get; }

`NativeGCEnabled` — Native array GC enabled flag
`boolean`

Syntax

public static bool NativeGCEnabled { get; set; }

If the native array GC is enabled, a CLR garbage collection will take place transparently as required to remove instances of the MWArray class or one of its derived types that are no longer being referenced. This includes unmanaged memory allocated through explicit creation of MWArray types, as well as implicit instantiation of an MWArray via an implicit cast.

`NumberOfDimensions` — Number of dimensions in `MWArray`
positive integer

This property is read-only.

Syntax

public int NumberofDimensions { get; }

See ndims.

`NumberOfElements` — Number of elements in `MWArray`
positive integer

This property is read-only.

Syntax

public int NumberOfElements { get; }

Equivalent to prod(size(A)) for non-empty arrays. See numel.

Public Methods

`Clone`	Syntax public virtual Object Clone() Makes a deep copy of an `MWArray`. See the "=" operator in the MATLAB documentation.
`ConvertToNativeTypes`	Syntax public static Object[] ConvertToNativeTypes( MWArray[] src, Type[] specifiedTypes ) Converts an array of `MWArray` to types specified by user. Returns an object array with the converted types on success, otherwise throws an `ArgumentException`. This method should only be called from the generated implementation.
`Dispose()`	Syntax publicvoidDispose() Releases resources of the `MWArray` and the native `mxArray` that it encapsulates. This method allows for the explicit lifecycle control of an `MWArray` and its native MATLAB array.
`DisposeArray`	Syntax publicstaticvoidDisposeArray( Object_object ) This dispose method recursively frees the resources of the `MWArray` instances contained in the Object argument. If the object implements the `IDisposable` interface, it is freed by calling its Dispose method. If the object represents an array of objects that implement the `IDisposable` interface, each object in the array is freed via the dispose method. Finally, if the object represents a multi-dimensional array, the array is recursively processed to free each object contained in the array.
`Equals`	Syntax public override bool Equals( Objectobj ) Compares two `MWArray` instances for equality. Returns true if both arrays are equal.
`Finalize`	Inherited from `Object`
`GetHashCode`	Syntax public override int GetHashCode() Returns the hashcode of the `MWArray`.
`GetObjectData`	Syntax public virtual void GetObjectData( SerializationInfoinfo, StreamingContextcontext ) Parameters info Type: System.Runtime.Serialization.SerializationInfo Holds the data needed to serialize or deserialize the object. context Type: System.Runtime.Serialization.StreamingContext Describes the source and destination of the serialized stream. Implements ISerializable.GetObjectData(SerializationInfo, StreamingContext) Serialization function. The arguments for this function are supplied by the .NET serialization infrastructure.
`GetType`	Inherited from `Object`
`MemberwiseClone`	Inherited from `Object`
`ToArray`	Syntax public virtual Array ToArray() Returns a native .NET array containing a copy of data in the underlying MATLAB array. The returned array has the same dimensionality as the underlying MATLAB array. The elements of the returned array are converted according to default conversion rules. If the underlying MATLAB array is a complex numeric type, `toArray` throws an exception. If the underlying array is sparse, a full representation of the array is returned. Care should be taken when calling `toArray` on a sparse array with large row and column dimensions, as this action may exhaust system memory. If the underlying array is a cell or struct array, `toArray` is recursively called on each cell.
`ToString`	Syntax public virtual string ToString() Returns a formatted string representing the contents of the `MWArray`

Specialized Operators and Functions

These methods specialize standard MATLAB operators and functions for objects in this class.

`Implicit(Double to MWArray)`	Implicit cast from native double scalar value to `MWNumericArray`
`Implicit(String to MWArray)`	Implicit cast from native character string to `MWCharArray`
