C # Matlab calls each other

Test environment

VisualStudio2013/. net4.0

matlab2015b

The higher version of Matlab is easy to connect to other languages and does not require a bunch of configuration.  

Other languages interact with Matlab in a similar operation.

C # calls Matlab

Basic idea: The matlab function is packaged into DLL files, combined with MATLAB data support DLL (MWArray.dll), delivered to other language programs.

1,matlab side of the Operation

Write matlab functions:

function [result,m,n] = Getselfmultiplyresult (list)
% the product of the computed matrix and its transpose matrix
% test returns multiple results
result = List*list ' [m,n] = size end

· function result = Getselfsquareresult(list)
The result of calculating the square of each element of the matrix
result = list. ^2;
End

· Packaging functions:

· Locate the Library compiler (librarycompiler)

· Packaging functions
As shown,
1) Select the target type;
2) Add the function files that need to be packaged;
3) Rename the library name.  

3. Rename the class name, or add a class that assigns the class to which the function belongs. Complete the packaging operation.  

Export DLL

In the generated file, locate the "for_redistribution_files_only" folder, which contains

CalcMatResult.dll CalcMatResultNative.dll two dll files, all can be used.  

In addition,MWArray.dll in the matlab installation directory, refer to the path:

X:\program Files\matlab\r2015b\toolbox\dotnetbuilder\bin\win\v2.0\

· 1

You can also directly search directly using software such as everything.

2,C # End of the Operation

The C # end uses the two DLL files of MWArray.dll and CalcMatResultNative.dll .

· Add DLL Reference

· Demo Code

Using System;
Using calcmatresultnative; //Add Reference
Using MathWorks.MATLAB.NET.Arrays; //Add Reference

namespacecsharpmatlabdemo
{
    Span lang= "en-US" >class program
    {
         static void Main (string[ ] args
        {
             int[,] list ={{< Span lang= "en-US" >1},{2},{3},{4}}; //column vector

Mwarray Array = newmwnumericarray (list);

Calcmatresultnative.multiply multi= New Multiply ();
Object Resultobj =multi. Getselfmultiplyresult (3, array); 3 indicates the number of results returned, less than or equal to the actual number of return values of the MATLAB corresponding function
Object[] Resultobjs = (object[]) resultobj;

Double[,] calcresult= (double[,]) resultobjs[0];
double[,] Sizem = (double[,]) resultobjs[1];
double[,] Sizen = (double[,]) resultobjs[2];

Console.readkey ();
}
}
}

MATLAB calls C #

MATLAB calls C # more simple, First C # code compiled into a DLL library,matlab Direct reference can be called.

If it fails, check to see if the . NET version used is too high, whether the platform (x64/86) matches, and so on.  

Note Select the release version of the DLL (bebug version of C # can also be referenced, but not in C + +).

1.C # end Operation

Code

namespace matlabinterface
{
    Public Class Dialog
    {
        public static bool showselectmsg (string< Span lang= "en-us" > MSG, string title)
         {
            DialogResult r = MessageBox.Show (msg, title, Messageboxbuttons.yesno, messageboxicon.question);
            return r = = Dialogresult.yes;
       }

public string Msg { get; set;}

public void showmsg()
{
MessageBox.Show (MSG, "hint ", MessageBoxButtons.OK, messageboxicon.information);
}

}
}

2.matlab Operation

% call C # DLL

% reference absolute path
net. addassembly ( ' R:\Users\GrassPhy\Desktop\MatlabCsharpDemo\MatlabInterface.dll '

% static method call
select = Matlabinterface.dialog. showselectmsg ( "Please select ... ' hint ' if select
    disp ( ' yes ' else
    disp ( ' no ' end

% member Method invocation
Dialog = matlabinterface. Dialog ();
Dialog. MSG = ' hint information ';
Dialog. showmsg ();
