加载用于仿真的信号数据

加载用于仿真模型的信号数据

可以使用几种不同的方法将数据加载到模型中，包括：

根级输入端口 - 从工作区导入信号数据，使用输入配置参数将其导入到 Inport、Enable 或 Trigger 模块的根级输入端口。要将多个信号导入到根级输入端口中，请考虑使用根输入端口映射器工具。
From File 模块 - 从 MAT 文件读取数据，将数据输出为信号。
From Spreadsheet 模块 - 从 Microsoft^® Excel^® 电子表格或 CSV 电子表格读取数据，将数据输出为一个或多个信号。
Playback 模块 - 从工作区、文件或仿真数据检查器加载数据。
信源模块 - 添加一个信源模块（例如 Sine Wave 模块）以生成要输入到另一个模块的信号。
Signal Editor 模块 - 显示、创建、编辑和切换可互换场景。
持久数据 - 将大数据从 MAT 文件流式传输到模型中。

您可以通过文件、工作区变量或模型参数来创建输入信号数据。您可以从另一个信源使用上次仿真时记录的数据，也可以自己创建数据。要确定使用哪种信号加载方法，请参阅Comparison of Signal Loading Techniques。
