discretizing a continuous state-space model

How can I discretize this state-space model using MATLAB:

x°(t)=Ax(t)+BU(t)+g

[Souarv De]

%% STEP 1: Continuous State Space Model (CSSM)
sys = ss(A,B<C<D);

%% Convert CSSM to Discrete State Space Model (DSSM)
sys_dis = c2d(sys,Ts); % Where Ts is the sampling period

you can use ss function to create a discrete state space model

refer to https://www.mathworks.com/help/control/ref/ss.html

discreteSys = ss(A,B,C,D,Ts)

you should also linearize the state space equation with respect to equilibrium point.
