导入、导出和共享仿真数据

R2026b

从文件和工作区将数据导入仿真数据检查器，保存和共享仿真并分析结果

您可以从文件或 MATLAB 工作区将数据导入仿真数据检查器，以将数据与记录的仿真结果一起可视化、比较和分析。仿真数据检查器支持从文件（例如 CSV 文件、Microsoft^® Excel^® 文件、MDF 文件、MLDATX 文件和 Parquet 文件 (自 R2026b 起)）导入。您也可以编写自定义文件和工作区读取器以导入其他格式的数据。

要保存和共享您的数据并分析结果，请将运行数据和信号数据导出到 MAT 文件、Microsoft Excel 文件、Parquet 文件 (自 R2026a 起)、CSV 文件 (自 R2026b 起)或 VCD 文件 (自 R2026b 起)。您也可以保存和加载仿真数据检查器会话，以同时保留您的数据和绘图外观。

要与没有 MATLAB 的协作者共享结果，请创建一个仿真数据检查器报告。查看报告仅需要 Web 浏览器。对于比较结果，您也可以创建一个交互式比较报告，它允许您像在仿真数据检查器中一样分析比较。
