Hi everyone,
I'm solving an optimization problem using an external solver package. (CasADi to solve a model predictive control problem)
My system is modeled in Simulink and the package is imported in an embedded script as,
"import casadi.*"
When compiling the model I get the error message, "Import statements are currently unsupported" (I'm running R2017b)
Is there anyway around this issue for my version of matlab?

Hi. Did you find a solution to this? If I used interpreted fcn block in simulink then my model works but it is very slow. Have you been able to implement this with MATLAB fcn block?
Regards,
Saad

Hi, I have a solution.
I just put my code in a .m function file(e.g myfun.m) outside. And add
coder.extrinsic('import');
After that, call myfun in Simulink matlab-function, and add
coder.extrinsic('myfun');
Then, the error disappeared magically.
