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.Port Order- Maps in the order it appears in the file to the corresponding port number.

How logging state trajectories of a Simulink® model in a structure format can be better than the traditional method of logging states in an array format. The ordering of the states along the columns in the logged matrix depends on the block sorted order, which the Simulink software determines during model compilation. Various factors can affect the block sorted order, which can alter the ordering of the states.

Convert a harness model that uses a Signal Builder block as an input to a harness-free model with root inports. The example collects data from the harness model and stores it in MAT-files for the harness-free model. After storing the data, the example removes the Signal Builder block from the harness model and adds root inports to create a harness-free model. Then, the data in the MAT-files is mapped to the root inports of the model.

How Simulink models handle big data as input to and output from a simulation.
