Question

我正在努力在Matlab（2019a）中导入C ++（2017）dlls。

尤其是，由于我不熟悉C ++，因此我尝试创建在https://github.com/MicrosoftDocs/cpp-docs/blob/master/docs/build/walkthrough-creating-and-using-a-dynamic-link-library-cpp.md中定义的MathLibrary。我根据指南创建了该库，并同时编译了Debug和Release（x86），并且使用描述的MathClient进行的导入工作正常。

但是，我尝试通过以下方式在Matlab中导入库（在将所需的文件夹添加到当前路径之后）：

        if libisloaded('MathLibrary') == 0
           handle = loadlibrary('MathLibrary.dll','MathLibrary.h');
        end

并引发大量错误：

        Warning: Message from C preprocessor:
        cl : command line warning D9027: source file 'C:\Users\miche\source\repos\MathLibrary\Release\MathLibrary.lib' ignored
        cl : command line warning D9021 : no operation performed

        > In loadlibrary 
        Error loading library intermediate output follows.
        The actual error is at the end of this output.

        -I"C:\Users\user\source\repos\MathLibrary\Release"

        -Fe"MathLibrary_thunk_pcwin64.dll"

        C:\Users\miche\source\repos\MathLibrary\Release\MathLibrary.lib(2):
        error C2018: character '0x60' unknown

，然后像这样继续进行，但出现许多字符错误。我的代码有什么问题？我该如何解决？
