Hello,

I want to "have an array of inputs instead of constants" with the help of the "from_workspace block" to extend these models;

- Slope angle

- Wind speed

- Grip coefficient

m = 1400; %vehicle weight
alp_ang = 0.03; %inclined plane angle in radians
g = 9.81; %gravitational force
c = 0.013; %homogeneous pavement
b = 0.00000648; %tabular
v_wind = 1; %wind speed in m/s
cy = 0.28; %vehicle aero coefficient
sy = 2.2; %vehicle frontal surface
rho = 1.225; %air density in kg/m^3
m_eff = m*1.2; %effective vehicle weight, 1 + alpha=~0.2
grip_coeff = 0.8; %grip coefficient
P = 80000;  %maximum vehicle power in watts
Trq = 475;  %maximum vehicle torque
r_w = 0.25; %wheel radius
G = 3.35;   %gear/torque multiplication factor
MaxBrk = 10000; %maximum braking force

What is the problem you are encountering in doing so? There is no restriction I can see in the Simulink documenation that says the variable read from the workspace needs tob e a scalar.
