Multiple s-function blocks produce different outputs.
显示 更早的评论
Hi,
I am building a simulink model which contains a number of S-function blocks (let's say two for simplicity). These blocks all have the same C mex-file, but different parameter values. The problem is now that only one of these two blocks produces a correct output. Even if the parameters and inputs of both blocks are the same, the outputs don't match. (I have stored the parameters in the real work vector.)
Does someone have an idea on what could cause this problem?

Do the S-functions have tlc files too? Did you create a mask for the S functions? if so different masks or same?

Are you using static variables in the C code? If so, you need to replace them with work vectors. It might also be a good idea to debug your S-function to find out exactly what is going wrong.

Pieter: I don't know what else to suggest other than ask you to try debugging your code to narrow down the issue to specific snippets of code. :(
