谈谈Matlab与C/C++或C#的互调用（混合编程）

SampleProperties Class.

using System;

namespace netdoc

    class SampleProperties

        // string property

        private static string stringField = "The MathWorks";

        public static string stringProp

            get { return stringField; }

            set { stringField = value; }

        // read/write property

        private double doubleField = 8.9;

        public double doubleProp

            get { return doubleField; }

            set { doubleField = value; }

        // read-only property

        private double readField = 0;

        public double readOnlyProp

            get { return readField; }

        // write-only property

        private double writeField = 0;

        public double writeOnlyProp

            set { writeField = value; }

Create Object. Load the assembly and create object obj :

sampleInfo = NET.addAssembly('c:/work/NetSample.dll');


obj = netdoc.SampleProperties

MATLAB displays the object as follows:

obj =

  netdoc.SampleProperties handle

  Package: netdoc

  Properties:

      stringProp: [1x1 System.String]

      doubleProp: 8.9000

    readOnlyProp: 0

  Methods, Events, Superclasses

MATLAB displays the stringProp , doubleProp, and readOnlyProp properties, but not the writeOnlyPropproperty. MATLAB also does not display properties defined with the privatekeyword, such as stringField and doubleField .

View Property Values. To view the value of stringProp , type:

obj.stringProp

MATLAB displays:

ans =

The MathWorks

Use PropertyValues. To use the properties, type:

db1 = obj.doubleProp

db2 = obj.readOnlyProp

MATLAB displays:

db1 =

    8.9000

db2 =

Modify PropertyValues. To modify the properties, type:

obj.doubleProp = 5;

obj.writeOnlyProp = 6;

obj

MATLAB displays (in part):

obj =

  Properties:

      stringProp: [1x1 System.String]

      doubleProp: 5

    readOnlyProp: 0

To modify the static property stringProp , type:

NET.setStaticProperty('netdoc.SampleProperties.stringProp', ...

    'This is a static property');

newVal = obj.stringProp

MATLAB displays:

newVal =

This is a static property

Using .NET FieldsExample

The SampleFields class defines the followingfields:

· publicField

· protectedField

SampleFields Class.

using System;

namespace netdoc

    class SampleFields

        public Int32 publicField;

        protected string protectedField;

Create Object. Load the assembly and create object obj :

NET.addAssembly('c:/work/NetSample.dll')

obj = netdoc.SampleFields;

Modify Field Values. To set the value of the field publicField , type:

myValue = 3;

obj.publicField = myValue

MATLAB displays:

obj =

  netdoc.SampleFields handle

  Package: netdoc

  Properties:

    publicField: 3

  Methods, Events, Superclasses

The publicField property is of type Int32. When you set the value to myValue , which is of MATLAB type double, MATLAB automatically converts the value to the proper type, as described in PassingData to a .NET Object . Type:

class(myValue)

class(obj.publicField)

MATLAB displays:

ans =

double

ans =

int32

Limitations to Support of .NET Properties

You cannot pass a cell array to a property, or view protectedproperties in MATLAB.
