Hello,
I'm using MPT Studio to generate a controller for a system. I've never used it before. I wrote the System Dynamics, the System Constraints, the Penalties, the Reference point, the Prediction horizon; when I press the buttom Generate Controller, the message "CAT arguments dimensions are not consistent" appears on my screen. As a detail, it says the error is due to "horzcat". I checked matrices and arrays dimensions in the system model and they are OK according to the number of states, inputs and outputs. I really don't know what else I can do...it seems it isn't able to horizontally concatenate some arrays or matrices...can anyone give me an help? Thank you!

Contact the developers with code and data, i.e Michal Kvasnica
