打开MDF-files and access information about the file and its contents.

Read channel data from an MDF-file.

Read channel data applying conversion rules from an MDF-file and configure different reading options in MATLAB.

Work with unfinalized and unsorted MDF-files. The unfinalized MDF-file used in this example, MDFUnfinalized.MF4, was recorded by a CANedge2 CAN bus data logger from CSS Electronics.

将时间表数据写入MDF文件。在此示例中使用的MDFTIMETABLES.MAT中使用的MAT文件包含两个时间表。

Custom set file, channel group, and channel metadata when writing timetable data to an MDF-file. The MAT-file used in this example MDFTimetables.mat contains two timetables.

Process data logged in a channel group of an MDF-file and write the updated data back to the same channel group. The MDF-file used in this example VehicleData.mf4 contains data logged from two simulations in two channel groups, but the example only works with data in channel group 1.

Process data logged in a channel group of an MDF-file and write the updated data to a new file. The MDF-file used in this example VehicleData.mf4 contains data logged from two simulations in two channel groups, but the example only works with data in channel group 2.

Add attachment files to an MDF-file, remove attachment files from an MDF-file, and save attachment files embedded in an MDF-file to disk. The MDF-file used in this example VehicleData.mf4 currently has one embedded attachment named ReadMe.txt.

Import and decode CAN data from an MDF-file in MATLAB® for analysis, and write the decoded data back to the same file. The MDF-file used in this example was generated from Vector CANoe™ using the "CAN - General System Configuration (CAN)" sample. This example also uses the CAN database file, PowerTrain.dbc, provided with the Vector sample configuration.

从MATLAB中的MDF文件中导入并解码J1939用于分析的数据。此示例中使用的MDF文件是使用“系统配置（J1939）”示例从向量独木舟生成的。此示例还使用CAN数据库文件，PowerTrain_J1939_MDF.DBC，并提供了矢量示例配置。

利用the MDF datastore feature of Vehicle Network Toolbox™ to quickly and efficiently process a data set spread across a collection of multiple MDF-files. This workflow is also valuable when there are too much data to fit into available memory.

使用高阵列和MDF数据存储功能使用大数据集。高阵列通常用于对不适合内存的不同类型的数据进行计算。

在出院模式下，通过各种驱动循环调查车辆电池电量。该分析的数据包含在一组MDF格式的车辆日志文件中。在此示例中，我们需要建立一种机制，该机制在车辆电池处于给定模式时可以“检测”。我们真正正在做的是建立一个检测器，以确定何时感兴趣的信号（在这种情况下电池电量）符合特定的标准。当满足标准时，我们将称之为“事件”。每个事件将随后通过施加时间范围来“合格”。也就是说，如果事件持续至少5秒钟（这样的资格步骤可以帮助限制噪声并消除瞬变），则该事件是“合格的”。此示例中显示的阈值仅是说明性的。

Programmatically map channels from MDF-files and consume their data via input ports of a Simulink model. It performs the gathering of input port names of a Simulink model and correlates them to the content of a given MDF-file. A linkage between them is then created which consumes channel data sourced from the MDF-file when the model runs.
