C # mixed programming with MATLAB

(Vs2005 + MATLAB 7.5) DLL production steps: star -- MATLAB builder. net -- deployment tool -- New -- MATLAB builder. net --. NET component -- Right-click Add file -- find the target M file -- compile

Reference in vs2005: reference the compiled DLL and keep *. CTF in the same folder.

Mwnumericarray is the intermediate class of data in mwarray and C #. how to use it? How to transmit parameters between C # and MATLAB?
A. Variable transfer for numeric types such as double and int
Mwnumericarray I = NULL, result = mydouble;
I = 4;
Myclass = new myclass (); // instantiate
Result = (mwnumericarray) myclass. myfunc (I );

B. String (requires mwchararray and mwarray conversion)
Mwchararray filename = mystring;
Mwnumericarray sensiti.pdf;
Sensitivity = (mwnumericarray) myclass. myalgorithm (mwarray) filename );

C. An array composed of multiple output parameters
Mwnumericarray out_arr = (mwnumericarray) out_args [1]; // retrieve the array returned by the first parameter (the lower bound of the array returned by MATLAB starts from 1)

Extracts an element value from the array.
Mydouble = out_arr [I]. toscalardouble ();

For example, there are many methods such as toxxxx in the toscalardouble class in the above example.

D. Result. toarray can convert the matrix returned by MATLAB to the N x m array of C #. For example:

Double [,] csarray = (double [,]) result. toarray (mwarraycomponent. Real );

E. Pass the array into MATLAB (same as the method for passing a single value)
Double [,] DBX = new double [2, 2] {1, 2}, {3, 4 }};
Mwnumericarray x = DBX;
Myclass. Picture (X );

 

How to receive and return m Files?

Function x = test (H, d) // receives two parameters and returns one

Function [x1, x2] = test (H, d) // returns an array

 

The above is a. net connection, and the following is a COM connection (for compilation speed, the. NET method is much faster and seems stable)

MATLAB Compilation
-Mbuild-Setup
-Deploytool, Matlab builder for. net, generic COM Component
-Add the m function file (eg: myfunc. m), change the class name (eg: mycomclass), and build

Register DLL
Regsvr32 mycom. dll
Regsvr32 mwcomutil. dll

Vs2005 call:
-Reference and COM controls
-Call example
Double [,] arr = NULL;
Object in_a, out_a;
In_a = 500;
Out_a = arr1;
Mycom. mycomclass MC = new mycom. mycomclass ();
MC. myfunc (1, ref out_a, in_a );

 

Example: (extract two parameters returned by MATLAB and convert them to a matrix of C)

Code
Testz. testzclass ST = new testz. testzclass ();
Mwarray [] Max = ST. testz (2 );
Mwnumericarray X1 = (mwnumericarray) Max [0];
Mwnumericarray X2 = (mwnumericarray) Max [1];
Double [,] location1 = (double [,]) x1.toarray (mwarraycomponent. Real );
Double [,] location2 = (double [,]) x2.toarray (mwarraycomponent. Real );
Label1.text = location1 [1, 2]. tostring ();

M file: Code
Function [x1, x2] = testz ()
X1 = [1 2 3;
4 5 6;
7 8 9;];
X2 = [9 8 7;
6 5 4;
3 2 1;];
