本文档介绍了在Win10系统中运行Datcom气动解算软件时可能出现的错误及其解决方法，包括修改环境变量和Datcom.bat文件。此外，还提供了MATLAB与Datcom交互的代码示例，以及Datcom的手册和相关资源下载链接。
版本说明
免费版本仍然可用。尚未使用Datcom + Pro版本的功能进行更新。没有大量的工作，我无法生成新的分发程序包，并且我现在对此不感兴趣。建议您观看教程视频，以了解使用新的Datcom + Pro有多么容易。 您将看到这个新软件包的功能强大，并节省了免费版本的时间。您会发现， 与免费版本相比，使用Datcom + Pro软件包更有效。
一旦安装，运行DATCOM +或DATCOM + Pro程序，你只要在DATCOM一个输入文件双击（用。DCM在Examples目录扩展名）。如果仅尝试单独运行digdat.exe程序，它将无法正确运行，并显示错误消息，例如“打开：没有这样的文件或目录”和“表观状态：名为for005.dat的单元5”。
WIN10报错解决办法
一些在Windows 10下运行免费版Datcom +的用户报告了问题，当他们双击.DCM文件时出现一条消息，提示“文件中存在错误：Citation.dcm ”，但并非所有用户都遇到此问题。我还没有弄清楚什么时候被触发的。如果您遇到这种情况，请按照下列步骤操作：
-
安装Datcom +软件包后，按Windows键+ r。键入“ SystemPropertiesAdvanced.exe”。
-
单击环境变量框。
-
更改DATCOMROOT的环境变量，删除前导和尾随双引号。保存并摆脱困境。
-
在桌面上的Datcom \ bin目录中，编辑Datcom.bat文件。在第14、15和16行上，删除双引号（前导和尾随）。
设置 PREDAT_PROGRAM = “ predat ”
设置 DATCOM_PROGRAM = “ digdat ”
集 DATCOM_MODELER_PROGRAM = “ DATCOM -modeler ”
- 您现在应该可以运行程序了。
手册
这些是Datcom原始手册的PDF文件，Digital Datcom程序基于3070页的方程式和方法。并非所有纸质手册都在计算机程序中表示。

% 以下是USAF Digital DATCOM的示例输入文件，其机翼-水平-水平尾部-垂直尾部配置在五个alpha，
% 两个马赫数和两个高度上运行，并计算静态和动态导数。
type astdatcom.in
% USAF Digital DATCOM针对在5个alpha，两个Mach数和两个高度上运行的相同机翼-水平-水平尾部-垂直尾部配置生成的输出文件
type astdatcom.out
% 使用datcomimport函数将Digital DATCOM数据带入MATLAB环境。
alldata = datcomimport('astdatcom.out', true, 0);
ex1data = datcomimport('ex1.out', true, 0);
data = alldata{1}; %数据提取
% 默认情况下，缺少的数据点设置为99999，而数据点设置为NaN在不存在DATCOM方法或该方法不适用的情况下。
% 可以在Digital DATCOM输出文件中看到并检查导入的数据，发现C仅在第一个alpha值中包含数据。 这是导入的数据值。
% data.cyb;
% 丢失的数据点将使用第一个alpha值填充，因为这些数据点将用于所有alpha值。
% 替换示例
