单步仿真问题

Royce

请教高手！Simulink 问题！！
建立一个模型，然后一步一步仿真，我想要每输入一个（或一组）数据，然后从模型中得到一个（或者是和输入同维的）输出。而且输出要和所有数据一齐输入时得出的结果一致。请教高手。是不是用下面的函数，怎么用？帮助说的很让人迷惑。
[sys,x0,str,ts] = model(t,x,u,flag);
This command is intended to allow linear analysis and other M-file program-based tools to run a simulation step by step, gathering information about the model's states and outputs at each step. It is not intended for interactive use, for example, to debug a model.
Use this command if you want to write an M-file program that needs to examine intermediate results of a simulation. Use the sim command if the program does not need to examine intermediate results. Use the Simulink debugger if you need to examine intermediate results to debug a model.
