How to use state-space block in simulink with one input

4 views (last 30 days)
Hi I am using state-space block in simulink. I am having two inputs;so I have used a mux but state-space block is not accepting it because input becomes a row vector and I need a scalar value as an input to the state-space block. What should I do to make it a scalar value. Any guidance or help will be greatly appreciated.

Actually the input should be in column vector form. Try to transpose the row vector. And also the size of the matrix A, B ,C and D are important so that the system works

you have said that you have two inputs, then i can guess that the size of B is nx2, n is the order of your system. in this case, you can use a "Mux" block

Thank you I got the hint from the second point of your comment.Actually I am taking Matrix B to be of 4x1 and it should be of 4x2.
