css - FlightGear“致命异常无效字符串位置”运行 NASA 的 MATLAB 内置 HL-20 模型

Question

我一直在尝试运行 MATLAB 的 Aerospace 模块组的预配置 HL-20 模型。它应该在 FlightGear 中运行，但我遇到了“致命异常：无效字符串位置”错误，我什至无法打开模拟。当我尝试按原样使用它时，以及当我尝试为我打算与 NASA 的模型一起使用的新飞机模型更改文档和代码的“hl-20”作为基础开始时，都会发生这种情况。此名称更改是 YouTube 上一个教程的后续，该教程似乎在那里工作得很好。我一直在使用 R2018a 版本的 MATLAB 和 2017.3.1 版本的 FlightGear。我应该编辑的代码是：
