I'm applying mpc for 2input, 1output system with 2states. and I'm unable to make the system state update.
For the above code I'm getting the error as
Error using *
Incorrect dimensions for matrix multiplication. Check that the number of columns in the first matrix
matches the number of rows in the second matrix. To perform elementwise multiplication, use '.*'.
Error in Bstwdmpcmov (line 75)
x = A*x + B1(:,1)*u;
please let me know, which corrections are needed..
thank you

Looks like the error is quite descriptive here, please check the dimensions of A, x, u, and B1 maybe by using a break point to see where the dimension mismatch is.

Since this is a separate question, ideally it should be on a new post for discoverability. In any case, the error in this case is also pretty helpful. The optimization problem you are asking MPC to solve becomes infeasible. Try again by relaxing the constraints or making them soft
