Hi,
I'm trying to simulate a power system model which has a m-file embedded into it. And, when I simulate it, I get the below error
Error reported by S-function 'sf_sfun' in '......':
Error calling generated SFunction, **.
Undefined function '****' for input arguments of type 'double'.
P.S.: "......" and "****" are the corresponding file names. I went through some of the previous threads, but couldn't figure out my error.
Thanks for the help.

Any help? :)

I know this is really late, but I am putting what I found here for googlers...
I just had the same error in 2015a, and it seems to be because I was setting the Simulink CodeGenFolder and CacheFolder parameters to nonstandard values. I'm not sure if there's a similar StateFlow value to set, but commenting out these lines from my setup file fixed the issue. So maybe it's something that you set up for Simulink that Stateflow is expecting in a different location?
% Simulink.fileGenControl('set', 'CacheFolder', [userpath '/_code_dummy_'], 'createDir', true)
% Simulink.fileGenControl('set', 'CodeGenFolder', [userpath '/_code_dummy_'], 'createDir', true)

when I am building the model, I too got one error i.e.,
Error reported by S-function 'SclXcp_Setup_sfun' in 'SwingEfence/Platform Configuration/SclXcp_Setup':
S-function parameter 4 must be a character string.
What it might be the reason ,can anyone help me out??

if someone need to solve it... i just found that if you change the language in the control plant and also in the function of simulink (the same that you use to change the simulation from batch to interctive it works
