您可以加载您在 MATLAB® 或电子表格中创建的信号数据，也可以加载在仿真期间保存的信号数据。您要加载的信号数据的类型将影响您要选择的信号加载方法。
有关如何在 Simulink® 模型中使用 MATLAB 数据、保存仿真数据以及记录信号以进行分析的概述，请观看加载和记录数据（4 分 9 秒）并参阅提供用于仿真的信号数据。
Create a custom mapping function for the Root Inport Mapper tool. The Root Inport Mapper tool associates MAT-file data with a specific input port, based on one of these criteria.
Logging states using the Structure format can provide advantages over the Array format. When you log states using the Array format, the ordering of the states along the columns in the logged array depends on the block sorted order. Various factors can affect the block sorted order, which can alter the ordering of the states from one simulation to the next. When you use the Structure format, the block names are stored along with the logged state data for that block, so you can process your data without considering the block sorted order.
Convert a harness model that uses a Signal Editor block as an input to a harness-free model with root input ports. The example uses data from the MAT-file of Signal Editor block of the harness model for the harness-free model. The example removes the Signal Editor block from the harness model and adds root input ports to create a harness-free model. Then, the data in the MAT-files is mapped to the root input ports of the model.
