So i am trying to linearize a System using a Jakobi Matrix. The linearization works fine but when i try to use the results with sys = ss(A,B,C,D) the Matrix A as well as the Vektor C seem not to be the right type or rather form.
This is how the Matrix looks like
A =
[ 0, 1]
[ -3/100, -1]
And this is how it should look like
A =
-0.1250 0
0.1250 -0.1250
witch results in this Error Message
Error using ss (line 274)
The value of the "a" property must be a numeric array without any Inf's or NaN's.
Error in Aufgabe_2 (line 20)
sys = ss(A, b, cT, d);
Any suggestions on how to change the Matrix around?

Convert A to floating-point type before passing to ss()
sys = ss(double(A), b, cT, d);
