【问题描述】：

我正在尝试使用 MATLAB 编码器将 MATLAB 代码转换为 C++，但出现此错误：

缩进生成的 C 代码时出错

错误指向函数本身的名称，其中没有更多解释。有人可以告诉我这是什么错误吗？这是我要转换的功能：

        Report_M(i,j,2)=Report_In(i,j,2);
        Report_M(i,j,3)=0; % Cluster number that the point belongs to.
        Report_M(i,j,4)=0;
Report_In{i,j}

【问题讨论】：

您能用一个小的复制代码粘贴确切的错误消息吗？另外，你用的是哪个版本的matlab？
问题已解决。这个错误一定是由于 matlab 无法覆盖在 mex 制作过程中构建的文件。您应该退出 matlab，删除 coder 制作的文件并尝试再次运行 coder。 @LokeshA.R.无论如何。
也许您也可以添加解决方案。它将帮助其他有相同错误消息的人。
解决方案很简单，问题是当您使用 coder 从您的 matlab 代码构建 .mex 文件并运行它时，当您想在 matlab 代码中进行更改并再次构建它时，您可以面对这个错误。我认为这种情况只有在您的 .mex 代码因错误而停止工作时才会发生。我认为 MATLAB 不会以某种方式关闭它正在运行的 .mex 文件，因此您无法重建它。在这种情况下，如果您尝试从工作区中删除 .mex 文件，您会注意到它说权限被拒绝，因此您只需关闭 matlab 并删除 .mex 文件并再次运行 matlab。希望对您有所帮助。
@Brokenlink，非常感谢，我从来不会这么想

【解决方案1】：

从您在 cmets 中所说的来看，您似乎只需要调用

clear functions

在重新编译函数之前从命令行中允许 Matlab 覆盖文件。有关详细信息，请参阅this Matlab 论坛或clear 的文档。
