here are my matrices a=[-50 -66.67;47.9 -1]; b=[83.33;0]; c=[0 0;0 1]; d=[0;0];
i want to get the the tf from the state space model. when tried to get it with input as 1 got a result which is- [num,den]=ss2tf(a,b,c,d,1)
num =
1.0e+003 *
0 0 0
0 0.0000 3.9915
den =
1.0e+003 *
0.0010 0.0510 3.2435
i am unable to get the answer.

From your data we can see that your system has one input (b is mx1) and two output (c is 2xm) then, from input 1 you have two transfer functions. Because c(1,:) is [ 0 0], the first transfer function is equal to 0. The result you've got is correct. What are you expecting as result?
