我在做simulink做仿真时出现两个错误：
1、Invalid setting for input port dimensions of 'untitled/Demux'. The dimensions are being set to [-1]. This is not valid because the total number of input and output elements are not the same.
2、Error in port widths or dimensions. Invalid dimension has been specified for output port 1 of 'untitled/State-Space'.
我是刚开始学matlab，对这个软件不太熟悉，如果哪位仁兄知道的话，麻烦指教一下，谢谢！:lol:
