【求助】请教各位高手

我编写了一个有关电机的s-function，导入simulink,又加了一些外部连线，此时运行良好。但是将上述图形封装后，放入一个大的仿真系统中就会报错：
Output returned by S-function MT_G' in block 'simulink1/Subsystem/S-Function' during flag=3 call must be a real vector of length 16；
State derivatives returned by S-function ‘MT_G' in block 'simulink1/Subsystem/S-Function' during flag=1 call must be a real vector of length 11。
百思不得其解，希望各位高手指点一二
