Can you please explain, how do you call the sim() command wihtin your c# app?
I tried to do the same, but it won't work. Always getting this error msg:
"MWMCR::EvaluateFunction error: Undefined function or method 'sim' for input arguments of type 'char'.Error in =>start_and_write.m at 3."

Well in line 3 you can find the sim-command. The function works fine in MATLAB but not as an .net assembly...

Code:

function [success] = start_and_write()
sim('MyModel.mdl')
save Output.mat
if exist('Output.mat','file')
success = 1;
else
success = 0;
end
