保存仿真的运行时数据

将仿真数据保存到 MATLAB^® 工作区；记录信号；导出信号、时间、输出和状态数据

您可以在仿真过程中将信号值保存到 MATLAB 工作区，或保存到 MLDATX 文件、MAT 文件或 Excel^®，以便于以后进行检索和后期处理。保存仿真数据也称为记录或导出仿真数据。

Dataset 格式为各种记录方法所记录的结果提供了一种通用的格式，因此以这种方式保存仿真数据可以简化后期处理。可以使用 Dataset 格式将数据存储为 MATLAB timeseries 对象，以便使用 MATLAB 进行处理。

Simulink^® 提供了转换工具，可以将记录的数据转换为 Dataset 格式。

要确定应该使用哪种方法来记录信号数据，请参阅导出仿真数据。
