MathWorks.MATLAB.NET.Arrays.MWStructArray Class

Namespace: MathWorks.MATLAB.NET.Arrays

Managed representation of MATLAB structure array

Description

MWStructArray is the managed representation of the MATLAB structure array. Like its MATLAB equivalent, it consists of field values associated with field names.

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.

Properties

Public Properties

ArrayType — Derived type of MWArray

Read-only: 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

Read-only: positive integer

This property is read-only.

Syntax

public virtual int[] Dimensions { get; }

See size.

Empty — Return writeable version of empty MWStructrray

Read-only: MWStructArray

This property is read-only.

Syntax

public static MWStructArray Empty { get; }

IsCellArray — Flag indicating if MWArray is MWCellArray

Read-only: boolean

This property is read-only.

Syntax

public bool IsCellArray { get; }

See iscell.

IsCharArray — Flag indicating if MWArray is MWCharArray

Read-only: boolean

This property is read-only.

Syntax

public bool IsCharArray { get; }

See ischar.

IsDisposed — Handle status of encapsulated MWArray

Read-only: boolean

This property is read-only.

Syntax

public virtual bool IsDisposed { get; }

IsEmpty — Flag indicating if MWArray is empty

Read-only: boolean

This property is read-only.

Syntax

public virtual bool IsEmpty { get; }

See isempty.

IsLogicalArray — Flag indicating if MWArray is MWLogicalArray

Read-only: boolean

This property is read-only.

Syntax

public bool IsLogicalArray { get; }

See islogical.

IsNumericArray — Flag indicating if MWArray is MWNumericArray

Read-only: boolean

This property is read-only.

Syntax

public bool IsNumericArray { get; }

See isnumeric.

IsStringArray — Flag indicating if MWArray is MWStringArray

Read-only: boolean

This property is read-only.

Syntax

public bool IsStringArray { get; }

See isstring.

IsStructArray — Flag indicating if MWArray is MWStructArray

Read-only: 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

Read-only: 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

Read-only: positive integer

This property is read-only.

Syntax

public int NumberofDimensions { get; }

See ndims.

NumberOfElements — Number of elements in MWArray

Read-only: positive integer

This property is read-only.

Syntax

public int NumberOfElements { get; }

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

NumberOfFields — Number of fields in MWArray

Read-only: positive integer

This property is read-only.

Syntax

public int NumberOfFields { get; }

Methods

Public Methods

Clone	Syntax public virtual Object Clone() Makes a deep copy of an MWArray. See the "=" operator in the MATLAB documentation.
Dispose()	Syntax public void Dispose() 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.
Dispose(Boolean)	Syntax protected override void Dispose( bool disposing ) Parameters disposing Type: System.Boolean Client explicit dispose flag Internal dispose function
DisposeArray	Syntax public static void DisposeArray( 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
GetField(String)	Syntax public MWArray GetField( string fieldName ) Parameters fieldName Type: System.String The field name. Return Value Type: MWArray The contents of the specified field. Returns the contents of the specified field in the structure array.
GetField(String, Int32)	Syntax public MWArray GetField( string fieldName, int index ) Parameters fieldName Type: System.String The field name. index Type: System.Int32 The index for an array of structures. Return Value Type: MWArray The contents of the specified field. Returns the contents of the specified field in the specified structure of an array of structures.
GetHashCode	Syntax public override int GetHashCode() Returns the hashcode of the MWStructArray (Overrides MWArray.GetHashCode().)
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
IsField	Syntax public virtual Array ToArray() Parameters fieldName Type: System.String The field name. Return Value Type: Boolean true if the field name is the name of a field in the structure array. Returns true if the specified field is the name of a field in the structure array.
MemberwiseClone	Inherited from Object
RemoveField	Syntax public MWStructArray RemoveField( string fieldName ) Parameters fieldName Type: System.String The field name. Return Value Type: MWArray The new structure array. Removes the specified field from the structure array.
SetField	Syntax public void SetField( stringfieldName, MWArrayfieldValue ) Parameters fieldName Type: System.String The field name. fieldValue Type: Mathworks.MATLAB.NET.Arrays.MWArray The field value. Sets the contents of the specified field in the structure array.
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 Array ToArray() Returns a formatted string representing the contents of the MWArray

Specialized Operators and Functions

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
