S-function flag calling from other functions

Hi,

Is there anyway to call the mdlInitializeSizes() function from any other function in the matlab level 1 S-function. Thanks

I guess you could technically call it from any other method in the same S-function, just like you can call a MATLAB sub-function from the main or any other sub-function in a file. However, in case of an S-function, it is recommended that you let the Simulink engine call it at the right time. Is there a reason that you want to do this?

Thanks for your answer. I want to do this because I want to go back to the initialization function to set my initial values again after a clear function.

Do you mean that you want to reset your states? This can only be done in the mdlUpdate method AFAIK. Where is your clear function called from? Note that the return value of the flag stage is important - for example, in mdlOutputs, only outputs can be returned and in mdlUpdate, only states can be returned.
