使用“在matlab中创建的dll"；在C#中 [英] problem with using a " dll created in matlab" in c#

问题描述

hi
我需要一些有关matlab编译DLL的调用的帮助(
下的C# deploytool). matlab函数是一个简单的函数，需要两个double并返回a
第三...

我向我的C#项目添加了必要的引用...

及其我的代码:

hi
I Need some help with the calling of a matlab compiled DLL (C# under
deploytool). The matlab function is a simple function THAT takes two double and return a
third...

i add necessary references to my c# project ...

and its my code :

Sum.Class1 a = new Sum.Class1();
           MathWorks.MATLAB.NET.Arrays.MWArray[,] s=new MWArray[1,3];

           a.sumab(2, 5, s);

             listBox1 .Items.Add(s);

方法(sumab)返回void，我不知道如何获得输出...
我非常赞

如果我只写a.sumab(2,5);
它给了我一个错误:

"

the method (sumab) return void and i dont know how can get my output ...
im very amazing

if i just write a.sumab(2,5);
it gives me an error:

"

... MWMCR::EvaluateFunction error ...
Error using ==> sumab
Too many output arguments..

"

请帮助我的朋友
tnx很多

please help me friends
tnx a lot

推荐答案

似乎至少调用了DLL中的函数.但是当然，如​​果函数需要3个参数，则调用

It seems the function in the DLL is at least called. But of course if the function expects 3 Parameters the call

a.sumab(2,5);

会产生错误.通常在matlab中，如果要从函数返回值，可以将其称为

will produce an error. Usually in matlab if you want a return value from a function you call it

s = a.sumab(2, 5); 

，因为matlab没有参考参数.

我认为您应该重写您的Matlab函数，使其仅包含2个参数，并且当然会返回结果总和.

参见例如:
http://thinkmetric.com/tuts/matlab/functions.html [

since matlab doesnt have reference parameters.

I think you should rewrite your Matlab function so that it only excepts 2 parameters and of course returns the result sum.

See for example:
http://thinkmetric.com/tuts/matlab/functions.html[^]

But then again why even use Matlab for such a simple task...
